Calculate the deflection of a particle thrown up to reach a maximum height zo, and that of a particle dropped from rest from the same height, due to the Coriolis force. For simplicity, you can assume that the particle was thrown straight up from the equator.

A solar collector is a device that is designed to collect solar radiation and convert it into heat energy. Heat losses can occur in the collector due to a variety of factors such as convection, radiation, and conduction. The heat loss is a significant factor that can impact the overall efficiency of the solar collector.

Convection heat losses occur due to the transfer of heat energy from the collector surface to the air or fluid that surrounds it. In order to minimize convection heat losses, the collector is typically designed with a glazing material that reduces the flow of air across the surface of the collector. This can be achieved through the use of a double-glazed or vacuum-sealed panel.

Radiation heat losses occur due to the emission of thermal radiation from the surface of the collector. This can be minimized through the use of materials that have low emissivity. These materials reflect a greater amount of solar radiation and reduce the amount of thermal radiation that is emitted from the surface of the collector.

Conduction heat losses occur due to the transfer of heat energy from the collector surface to the surrounding environment. This can be minimized through the use of insulation materials that prevent the transfer of heat energy.

Overall, the design and construction of the solar collector play a significant role in minimizing heat losses and increasing efficiency. By reducing heat losses, the collector can more effectively convert solar radiation into heat energy, which can then be used for a variety of applications such as heating water or generating electricity.

A heating cooling curve shows the changes that occur when heat is added to or removed from a sample of matter at a constant rate, A) Heat, constant

A heating cooling curve illustrates the changes that take place when heat is added to or removed from a sample of matter at a constant rate. This curve depicts the relationship between the temperature of the substance and the amount of heat energy it absorbs or releases.

During the heating phase, the substance absorbs heat energy, causing its temperature to increase. As the temperature rises, the substance undergoes phase transitions, such as melting or boiling, where heat is absorbed without a significant change in temperature. These transitions are represented as horizontal plateaus on the heating curve.

On the other hand, during the cooling phase, the substance releases heat energy, resulting in a decrease in temperature. Similar to the heating phase, phase transitions occur during cooling, with heat being released without a change in temperature.

The heating cooling curve provides valuable information about the thermal properties and behavior of a substance. It allows us to determine specific heat capacities, latent heat of fusion or vaporization, and the temperature range over which a substance remains in a particular phase.

1. The apparent depth of an object submerged in a medium can be calculated using the formula: apparent depth = real depth / refractive index.

In this case, the real depth of the fish is 20 cm and the refractive index of water is 1.33. Substituting the values into the formula: apparent depth = 20 cm / 1.33 = 15.04 cm. So, the apparent depth of the fish, when viewed at normal incidence, is approximately 15.04 cm. 2. To determine how far from the surface of the water the lamp appears to the fish, we need to consider the concept of refraction. The apparent distance of an object above the water surface can be calculated using the formula: apparent distance = real distance / refractive index. In this case, the real distance from the lamp to the water surface is 80 cm, and the refractive index of water is 1.33. Substituting the values into the formula: apparent distance = 80 cm / 1.33 = 60.15 cm. So, the lamp appears to be approximately 60.15 cm from the surface of the water when viewed by the fish.

Initial volume (Vi) of the ideal monoatomic gas of 9.33 moles is 103.57 L.

Change in internal energy of gas is zero.

Using the Ideal Gas Law equation, PV = nRT, we can obtain an expression relating the initial volume to the other parameters as shown below:

PiVi = nRTi

The same expression can be obtained for the final state of the gas, using the values for the final pressure, volume, and temperature as follows:

PfVf = nRTf

Since the process is isothermal, the temperature is constant, and we can equate the right-hand sides of these two expressions:

PiVi = PfVf

Rearranging the above equation, we get:

Vi = PfVf / PiVi = 10 x 29 / 2.8 = 103.57 L

The change in internal energy of the gas (ΔU) is given by the formula:

ΔU = nCvΔT where Cv is the molar specific heat at constant volume, and ΔT is the change in temperature.

Since it is an isothermal process, there is no change in temperature, i.e., ΔT = 0.

The center of gravity for a female subject with Body Weight = 125 lbs and a reading on the scale with arms at her side of F21 = 86 lbs is 101.4 cm.


The formula for finding the center of gravity is d1 = (Lub x F21) / Wb where, L is the total length of the board, Lub is the length of the upper board, Wb is the weight of the board, F21 is the force exerted on the board by the subject, and d1 is the center of gravity distance in cm.

Given data: Body Weight = 125 lbs, F21 = 86 lbs, Lub = 99 cm, Wb = 218.1 N, and BH = 65 inches

We need to convert Body Weight from pounds to newtons:

125 lbs = 56.7 kg
(Weight in pounds) / 2.205 = (Weight in kg)

The weight of the subject is 56.7 kg

Average velocity of the particle between t = 0s and t = 2s is:Velocity = ∆distance / ∆timeTherefore, the average velocity is (s(2s) - s(0s)) / (2s - 0s) = (40m - 0m) / 2s = 20m/sii) Momentary velocity of the particle at time t = 1s is:v = ds/dtTherefore, the momentary velocity is v(1s) = ds/dt (1s) = 20t(1s) = 20m/sb).

Given that m = 2kg, we are required to calculate the net force (resultant force) acting on the particle at time t = 2s.We know that:F = m * awhere F is force, m is mass and a is acceleration of the particle. The acceleration is the second derivative of the position, which is

a = d2s/dt2.

We have:s(t) = 10t2∴ v(t) = ds/dt = 20t∴ a(t) = dv/dt = 20m/s2For t = 2s, the acceleration a(2s) = 20m/s2.

Therefore, the net force is

F = m * a = 2kg * 20m/s2 = 40 N

c) The first law of Newton states that if no external force is applied on a body, it will remain at rest or continue to move at a constant velocity in a straight line. The second law of Newton states that the net force acting on an object is proportional to the rate of change of its linear momentum. These laws can be used to answer the following:If you are on frictionless horizontal ice and standing still at a point A, and another point B is several meters away and you want to get there, can you manage to reach point B if you only take a strong enough rate?Justify the answer briefly (the justification should be based on Newton's laws).Yes, you can manage to reach point B if you only take a strong enough rate.

When you take a step on the ice, your feet push the ice backwards. As a result, the ice pushes your feet forwards. This reaction force allows you to move forwards. Since there is no external force on you, you will move at a constant velocity in a straight line until you reach point B.ii) Now assume that you take off your hat and stand on it when you make a bet. Can you now manage to get to point B (without a hat)? Justify the answer briefly.No, you cannot manage to get to point B without a hat. By taking off your hat and standing on it, you reduce your mass and increase your acceleration.

According to the second law of Newton, the net force acting on an object is proportional to the rate of change of its linear momentum. Since your mass has decreased, the force required to move you has decreased. Therefore, to maintain the same acceleration, you need to apply a smaller force. However, as there is no external force to propel you forward, the force of your feet pushing backwards will also be reduced. This means that your acceleration and hence velocity will decrease, and you will not be able to reach point B.

The mass of the ice required to cool the tea to 10.0°C, considering the temperature change of the glass, is approximately 173 g.

To find the mass of the ice required, we need to consider the heat transferred between the tea, the glass, and the ice.

First, let's calculate the heat transfer between the tea and the glass:

q1 = mcΔT1

q1 = (0.350 kg)(0.837 kJ/kg-K)(10.0°C - 95.0°C)

q1 = -80.32 kJ

Next, let's calculate the heat transfer between the ice and the glass:

q2 = mcΔT2

q2 = (0.350 kg)(0.837 kJ/kg-K)(10.0°C - (-10.0°C))

q2 = 23.38 kJ

Now, let's calculate the heat transferred during the phase change of the ice:

q3 = mhf

q3 = (m)(333.7 kJ/kg)

q3 = 333.7m kJ

Since the total heat transferred must be zero (assuming no heat is lost to the surroundings), we can set up the equation:

q1 + q2 + q3 = 0

Substituting the calculated values:

-80.32 kJ + 23.38 kJ + 333.7m kJ = 0

Simplifying the equation:

333.7m = 57.94

m ≈ 0.173 kg

Converting to grams:

mass of ice = 0.173 kg * 1000 g/kg

mass of ice ≈ 173 g

Therefore, the mass of the ice required to cool the tea to 10.0°C, considering the temperature change of the glass, is approximately 173 g.

The turbine's power output is regulated by adjusting the pitch angle of the blades using a control algorithm to maintain a constant generator speed. An active pitch control mechanism helps to protect a wind turbine from over-speed in high winds, ensuring the safety of people and machines involved.

(a) Tip Speed Ratio The ratio of the speed of the tip of a wind turbine blade to the wind speed is known as the Tip Speed Ratio (λ). The value of the tip speed ratio influences the efficiency of the wind turbine in transforming wind energy into rotational mechanical energy. The rotor speed and pitch angle of the blade are both affected by the tip speed ratio. To keep the ratio constant and maintain high efficiency, the rotor speed and blade pitch angle must be adjusted to correspond to changes in wind speed. The ideal tip speed ratio is roughly 6, which is when the highest amount of energy is generated per unit of wind. A high tip speed ratio also raises the chances of a wind turbine's early breakdown due to mechanical failure.(b) Active Pitch ControlActive pitch control is a method used to regulate power output by controlling blade angle. This mechanism's operation entails modifying the blade angle to maintain the optimum operating speed for wind turbine efficiency. In addition, the active pitch system is employed to limit the wind turbine's power output when there is too much wind. This is accomplished by pitching the blades out of the wind to reduce their effectiveness.

vi is the initial velocity of the projectile as a vector, which has three components: one in the x-direction, one in the y-direction, and one in the z-direction. To determine these components, we must use trigonometry to find the horizontal and vertical components of the vector.

The horizontal component of the vector, vi, is 10*cos(30*pi/180), and the vertical component of the vector is 10*sin(30*pi/180).

PLCs can operate in two modes: real-time and non-real-time. The principle difference between real-time and non-real-time behaviour of PLCs is that PLC in real-time mode must execute operations as quickly and predictably as possible.Real-time PLCs have a quicker response time than non-real-time PLCs.

When a program is executed in real-time, the PLC must complete each instruction within a predetermined time frame to ensure that critical processes are completed correctly and without error in a timely manner. A real-time system's performance is measured by how quickly it can respond to a specific event or signal.

Non-real-time PLCs do not operate in this manner and execute instructions without any time restrictions or deadlines. Non-real-time PLCs are intended for applications that do not require immediate or rapid responses and where timing is not a critical factor. The system's performance isn't measured by how quickly it can react to an event or signal, but by how well it can execute a task without taking into account the time required for completion.

In conclusion, the primary distinction between real-time and non-real-time behaviour of PLCs is the responsiveness of the system. The PLCs in real-time mode respond quickly and predictably to specific events or signals, while those in non-real-time mode are intended for applications where timing is not critical and execute tasks at a pace that is not constrained by time.

Answer:

Power factor = 0.685

Average power delivered = 86.94 W

Power factor when the capacitor is replaced with an L = 0.292 H inductor = 0.182

Average power delivered to the circuit = 11.24 W

Total resistance = 40.9 Ω

Total reactance = 151.43 Ω

Average power dissipated in the circuit = 829.7 W

Given values,

R = 44.3 ΩC = 33.5

µF = 33.5 × 10⁻⁶

FAVRMS = 115

VF = 108 Hz

(a) Power factor in the circuit

The power factor is given by the formula:

cos(Φ) = R/Z

where Z is the impedance of the circuit.Z = √(R² + Xc²)

Where Xc = 1/2πfC

= 1/2π × 108 Hz × 33.5 × 10⁻⁶

= 48.07 ΩZ

= √(44.3² + 48.07²)

= 64.5 Ωcos(Φ)

= 44.3/64.5

= 0.685

(b) Average power delivered to the circuit

The average power P = VRMSIRMScos(Φ)

Where IRMS = VRMS/Z

= 115 V / 64.5 Ω

= 1.78 A

And P = 115 × 1.78 × 0.685

= 86.94 W

(c) Power factor when the capacitor is replaced with an L = 0.292 H inductor

Xl = 2πfL

= 2π × 108 Hz × 0.292 H

= 199.6 Ωcos(Φ)

= R/Z = 44.3 / √(44.3² + 199.6²)

= 0.182

(d) Average power delivered to the circuit now

IRMS = VRMS/Z

= 115/√(44.3² + 199.6²)

= 0.559 AP

= VRMSIRMScos(Φ) = 115 × 0.559 × 0.182

= 11.24 W

(e) Total resistance in the circuit

The RMS current

I = IRMS × sin(Φ)

= 6.58 × sin(53.5°)

= 5.55 A

The total resistance R = VRMS / I

= 227 V / 5.55 A

= 40.9 Ω(f)

Total reactance X = XL - XC

Where XL = 2πfL

= 2π × 0.292 × 108

= 199.5 ΩXC

= 1/2πfC

= 1/2π × 108 × 33.5 × 10⁻⁶

= 48.07 Ω

So, X = 199.5 - 48.07

= 151.43 Ω

(g) Average power dissipated in the circuitP

= VRMSIRMScos(Φ) = 227 × 6.58 × cos(53.5°)

= 829.7 W

The resistance of the resistor needed to limit the current in the field coil to 1 A is 295.5 Ω.

To calculate the resistance of the resistor needed to limit the current in the field coil of the DC generator, we can use Ohm's Law.

Ohm's Law states that the voltage (V) across a resistor is equal to the current (I) flowing through it multiplied by its resistance (R):

V = I * R

In this case, we want to limit the current to 1 A, and the source voltage is 295.5 V. The resistance of the field coil is given as 100 Ω.

To calculate the resistance of the resistor needed, we rearrange the formula as:

R = V / I

R = 295.5 V / 1 A

R = 295.5 Ω

Therefore, the resistance of the resistor needed to limit the current in the field coil to 1 A is 295.5 Ω.

2)  The atomic number of the decay product is 75.

Question 1:

If an element with atomic number 52 and atomic mass 209 undergoes beta plus (β+) emission, it means that a proton in the nucleus is converted into a neutron, resulting in the emission of a positron (β+) and a neutrino.

During beta plus decay, the atomic number decreases by 1 because a proton is converted into a neutron. Therefore, the atomic number of the decay product will be 52 - 1 = 51.

So, the answer to Question 1 is: The atomic number of the decay product is 51.

Question 2:

If an element with atomic number 77 and atomic mass 190 undergoes alpha (α) emission, it means that the nucleus emits an alpha particle, which consists of two protons and two neutrons.

During alpha decay, the atomic number decreases by 2 because an alpha particle, which contains two protons, is emitted. Therefore, the atomic number of the decay product will be 77 - 2 = 75.
