Explanation:

it's a archea so its unicellular

Electricity is supplied to a school along a cable of total resistance 0.5 ohms with the maximum current drawn from the mains as 100A. the maximum energy dissipated as heat for 1hr is 18,000,000 Joules (J).

The following formula may be used to determine the maximum energy that was lost as heat during one hour:

Power x Time equals Energy

where authority is granted by

I2R = Power

where R denotes the overall resistance of the wire and I denotes the current flowing through it.

Given that the maximum current drawn from the mains is 100A and that the total resistance of the cable is 0.5 ohms, we may determine the power wasted as follows:

5000W is equal to (100A)2 times 0.5.

We must convert one hour to seconds in order to determine the amount of energy lost throughout that time. Since 3600 seconds make up 1 hour, we have:

Time = 3600s

Therefore, the amount of energy that was lost as heat in an hour is:

So the maximum energy dissipated as heat for 1 hour is 18,000,000 Joules (J).

The total mechanical energy at point A is 617,400 J, and the velocity of the coaster at point A is 25 m/s, the velocity of the coaster at point B is 34.4 m/s. and the highest hill the coaster could have gotten over before point A with no additional mechanical energy is 63 m.

To solve this problem, we can use the conservation of mechanical energy, which states that the sum of kinetic energy and potential energy is constant in a closed system where there is no work done by non-conservative forces like friction. We can use this principle to find the answers to the questions.

a) The Total Mechanical Energy of the rollercoaster at Point A

The total mechanical energy of the rollercoaster at point A is the sum of its potential energy and kinetic energy. At point A, the rollercoaster is at its highest point, so its kinetic energy is zero. Therefore, the total mechanical energy at point A is equal to the potential energy, which is given by:

mgh = 1000 kg × 9.8 m/s^2 × 63 m = 617,400 J

b) The velocity of the coaster at point A

To find the velocity of the coaster at point A, we can use the conservation of mechanical energy principle again. At point A, all of the potential energy is converted into kinetic energy. Therefore, we can write:

1/2 mv^2 = mgh

where m is the mass of the rollercoaster, v is the velocity at point A, g is the acceleration due to gravity, and h is the height of point A relative to point E. Solving for v, we get:

v = sqrt(2gh) = sqrt(2 × 9.8 m/s^2 × 63 m) = 25 m/s

Therefore, the velocity of the coaster at point A is 25 m/s.

c) The velocity of the coaster at point B

To find the velocity of the coaster at point B, we can use the conservation of mechanical energy principle again. At point B, the rollercoaster is at a height of 42 m above the ground. Therefore, the potential energy at point B is:

mgh = 1000 kg × 9.8 m/s^2 × 42 m = 411,600 J

At point B, some of the potential energy is converted into kinetic energy, so we can write:

1/2 mv^2 + mgh = mgh_D

where v is the velocity at point B, h is the height of point B relative to point E, and h_D is the height of point D relative to point E. Solving for v, we get:

v = sqrt(2(mgh_D - mgh)/m) = sqrt(2(8780 J)/1000 kg + 2gh) = 34.4 m/s

Therefore, the velocity of the coaster at point B is 34.4 m/s.

d) The highest hill the coaster could have gotten over before point A with no additional mechanical energy

If the rollercoaster had no additional mechanical energy, its total mechanical energy at point A would be equal to its potential energy, which we calculated in part (a) to be 617,400 J. Therefore, the maximum height that the rollercoaster could reach without any additional mechanical energy is given by:

mgh_max = 617,400 J

Solving for h_max, we get:

h_max = 617,400 J / (1000 kg × 9.8 m/s^2) = 63 m

So, the highest hill the coaster could have gotten over before point A with no additional mechanical energy is 63 m.

Therefore, The coaster has a total mechanical energy of 617,400 J at point A, a velocity of 25 m/s, a velocity of 34.4 m/s, and a maximum hill height of 63 m that it could have traversed without using any further mechanical energy.

a) The force exerted by the right hind leg is 400 lb.

b) The position of the center of gravity of the horse is 6.67 ft from the left hind leg.

a) According to the problem, the total weight of the horse is 1000 lb, and the left hind and right forelegs each support 300 lb.

That means the weight supported by the right hind leg is:

Weight supported by right hind leg = Total weight - Weight supported by left hind leg - Weight supported by right foreleg

Weight supported by right hind leg = 1000 lb - 300 lb - 300 lb

Weight supported by right hind leg = 400 lb

Therefore, the force exerted by the right hind leg is 400 lb.

b) To calculate the position of the center of gravity of the horse, find the point where the weight of the horse can be considered to act. Assuming that the horse is symmetric, this point should be exactly halfway between the left and right legs that support the weight.

So, calculate the position of the center of gravity as follows:

Position of center of gravity = Distance from left leg to center of gravity

Distance from left leg to center of gravity = Distance from right leg to center of gravity

Distance from left leg to center of gravity = (Weight supported by right hind leg) × (Distance between legs) / (Total weight supported by both hind legs)

Distance from left leg to center of gravity = (400 lb) × (10 ft) / (600 lb)

Distance from left leg to center of gravity = 6.67 ft

Therefore, the position of the center of gravity of the horse is 6.67 ft from the left hind leg.

Explanation:

* **Step 1: Identify the relevant information.**

We are given the following information:

 * The initial velocity of the puck is 28.0 m/s horizontally.

 * The height of the platform above the ground is 2.00 m.

 * We can neglect air resistance.

* **Step 2: Set up the equations.**

We can use the following equations to solve for the direction of the velocity of the puck just before it hits the ground:

 * $v_y = v_0y + at$

 * $y = y_0 + v_0yt + \frac{1}{2}at^2$

Where:

 * $v_y$ is the final velocity in the vertical direction

 * $v_0y$ is the initial velocity in the vertical direction

 * $a$ is the acceleration due to gravity (9.8 m/s^2)

 * $t$ is the time

 * $y$ is the vertical position

 * $y_0$ is the initial vertical position

* **Step 3: Solve for the unknowns.**

We can solve for the final velocity in the vertical direction using the following equation:

```

v_y = v_0y + at

```

Plugging in the known values, we get:

```

v_y = 0 + (-9.8) t

```

```

v_y = -9.8t

```

We can solve for the time using the following equation:

```

y = y_0 + v_0yt + \frac{1}{2}at^2

```

Plugging in the known values, we get:

```

2 = 0 + (0) t + \frac{1}{2}(-9.8)t^2

```

```

4 = -4.9t^2

```

```

t^2 = -0.816

```

```

t = -0.90

```

We can now solve for the final velocity of the puck using the following equation:

```

v_y = -9.8t

```

Plugging in the known value for $t$, we get:

```

v_y = -9.8(-0.90)

```

```

v_y = 8.82 m/s

```

The final velocity of the puck in the vertical direction is 8.82 m/s downward.

* **Step 4: Find the angle.**

The angle of the velocity of the puck can be found using the following equation:

```

\theta = \tan^{-1} \left ( \frac{v_y}{v_x} \right )

```

Plugging in the known values for $v_y$ and $v_x$, we get:

```

\theta = \tan^{-1} \left ( \frac{8.82}{28.0} \right )

```

```

\theta = 12.6^\circ

```

Therefore, the direction of the velocity of the puck just before it hits the ground is 12.6 degrees below the horizontal.

The force on each side of the loop is 5.1 × 10^-5 N in the direction perpendicular to the wire and the magnetic field, and the direction of the force is determined by the right-hand rule.

The force on each side of the loop can be calculated using the formula F = BIL, where F is the force, B is the magnetic field, I is the current, and L is the length of the wire.

First, we need to find the magnetic field inside the solenoid. The magnetic field inside a solenoid is given by B = μ₀nI, where μ₀ is the permeability of free space, n is the number of turns per unit length, and I is the current.

In this case, the magnetic field inside the solenoid is B = μ₀nI = (4π × 10^-7 T·m/A)(25 turns/cm)(17.0 A) = 0.017 T.

Since the loop is perpendicular to the magnetic field, the angle between the current and the magnetic field is 90 degrees, and the force on each side of the loop is given by F = BIL. The length of each side of the square loop is L = 8.0 cm/4 = 2.0 cm.

Therefore, the force on each side of the loop is F = (0.017 T)(0.15 A)(2.0 cm) = 5.1 × 10^-5 N.

i) The slope of the line (m) would be ln(a), and the intercept (c) would be 0.

ii)  The slope and intercept obtained from the linearized equations provide valuable information about the relationship between the variables involved.

To linearize the given equations, we need to rewrite them in a linear form. Let's work through each equation:

(i) Y = aX¹

To linearize this equation, we can take the natural logarithm (ln) of both sides:

ln(Y) = ln(aX¹)

Using the logarithmic property, we can simplify it as:

ln(Y) = ln(a) + ln(X¹)

Now, we can introduce a new variable, let's say ln(Y), and rewrite the equation as:

ln(Y) = ln(a) + X¹ln(X)

Now, we have a linear equation in the form Y' = mX' + c, where Y' = ln(Y), X' = ln(X), m = ln(a), and c = 0. In this linearized form, Y' would be plotted on the y-axis, and X' would be plotted on the x-axis. The slope of the line (m) would be ln(a), and the intercept (c) would be 0.

(ii) C = aT + BT²

To linearize this equation, we can introduce a new variable, let's say Z, defined as Z = C/T. Now, we can rewrite the equation as:

Z = a + BT

Now, we have a linear equation in the form Z = mT + c, where Z = C/T, m = B, and c = a. In this linearized form, Z would be plotted on the y-axis, and T would be plotted on the x-axis. The slope of the line (m) would be B, and the intercept (c) would be a.

By linearizing the equations, we can transform the nonlinear relationships into linear relationships, which allows for easier analysis and interpretation of the data. The slope and intercept obtained from the linearized equations provide valuable information about the relationship between the variables involved.

(a) The initial gravitational potential energy of the lead can be calculated using the formula:

E = mgh

where E is the potential energy, m is the mass, g is the acceleration due to gravity, and h is the height. Substituting the given values, we get:

E = (0.5 kg) × 10 m/s² × 25 m = 125 J

Therefore, the initial gravitational potential energy of the lead is 125 J.

(b) When the lead reaches the ground, all of its potential energy is converted into kinetic energy. The kinetic energy can be calculated using the formula:

E = (1/2)mv²

where E is the kinetic energy, m is the mass, and v is the velocity. At the moment of impact, the lead has a velocity of:

v = √(2gh) = √(2 × 10 m/s² × 25 m) = 10 m/s

Substituting the given values, we get:

E = (1/2) × 0.5 kg × (10 m/s)² = 25 J

Therefore, the kinetic energy of the lead on reaching the ground is 25 J.

(c) The energy gained by the lead due to the impact is converted into internal energy, which raises the temperature of the lead. The amount of energy required to raise the temperature of the lead can be calculated using the specific heat capacity formula:

Q = mcΔT

where Q is the energy gained, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. The specific heat capacity of lead is 128 J/kg°C. Substituting the given values, we get:

125 J - 25 J = (0.5 kg) × 128 J/kg°C × ΔT

ΔT = (100 J) / (64 J/kg°C) = 1.56°C

Therefore, the rise in temperature of the lead is 1.56°C.

(d) The energy transfers that have occurred from the moment the lead strikes the ground until it has cooled to air temperature again are:

Conversion of potential energy to kinetic energy upon impact

Conversion of kinetic energy to internal energy upon impact, raising the temperature of the lead

Transfer of heat energy from the lead to the surrounding air, as the lead cools down to air temperature

At the given instant, the radial acceleration of the particle moving clockwise in a circle of radius 2.5 m is 21.650 m/s², its speed is 11.625 m/s, and its tangential acceleration is 12.5 m/s².

In circular motion, there are three important quantities: radial acceleration, tangential acceleration, and speed.

At the given instant, the radial acceleration (ar) can be calculated as:

ar = a cosθ

ar = 25 m/s² × cos30°

ar = 25 × 2/3

ar = 21.650 m/s²

The speed of the particle (V) can be calculated as:

V = r ×θ'

θ' = sqrt(rar/r)

θ' = sqrt(2.5×21.650/2.5)

θ' = sqrt(21.65)

θ' = 4.65 rad/s

V = r × θ'

V = 2.5 × 4.65

V = 11.625 m/s

The tangential acceleration (aθ) can be calculated as:

aθ = a sinθ

aθ = 25 m/s² ×sin30°

aθ = 25 × 1/2

aθ = 12.5 m/s²

Therefore, The particle is traveling clockwise in a circle with a radius of 2.5 m, its tangential acceleration is 12.5 m/s², its speed is 11.625 m/s, and its radial acceleration is 21.650 m/s².

I think the actual question is,

The figure shows( find at the bottom of this answer) the total acceleration and velocity of a particle moving clockwise in a circle of radius 2.5 m at a given instant of time. At this instant, find:

(a) the radial acceleration,

(b) the speed of the particle and

(c) its tangential acceleration.
