Answer: 45 m/s and 80 m/s

Explanation:

The acceleration due to gravity on an object is 9.8 m/s^2

Simply multiple this my the the time that it has fallen (in seconds) and this will provide you with its velocity at that time.

(4.5 seconds) (9.8) = 44.1 m/s

(8 seconds) (9.8) = 78.4 m/s

The average speed in km/h will be 93.342 km/hr for 58 mph.

Speed is defined as the ratio of distance and time, and average speed is defined as the overall distance the object covers in a given amount of time is its average speed. The scalar quantity represents the average speed. It does not have direction; it is represented by magnitude.

Average Speed=[tex]\frac{total distance}{total time}[/tex]

According to the question, the speed is given i.e., 58mph

1 mph=1.61 km/hr

⇒58 mph= 1.61×58

The sides of a small rectangular box are measured to be 1.80 ± 0.01 cm, 2.05 ± 0.02 cm, and 3.1 ± 0.01 cm long. Its volume and uncertainty is 11.4 ± 0.2 cm³.

While doing certain experiments or calculation we can end a less precise value that what actually it's the answer of the experiment, this exact value of the experiment is called true value.

In physics uncertainty refers to the possible variation from the true value. Variation is calculated for possible increment in the precision of the result.

These are the rules for doing basic operation on uncertainty :

If you're adding or subtracting quantities with uncertainties, you add the absolute uncertainties.

If you're multiplying or dividing, you add the relative uncertainties.

If you're multiplying by a constant factor, you multiply absolute uncertainties by the same factor, or do nothing to relative uncertainties.

Now in the given question we have to multiply the uncertainty, so we will simply add the relative error.

To find volume of the cubic structure we simply multiply the error free values.

Volume of the cuboid = Length × Breadth × Height

Volume of the cuboid = 1.80 cm × 2.05 cm × 3.10 cm

Volume of the cuboid = 11.4 cm³

Uncertainty in the volume[tex]= \frac{0.01\ cm}{1.80\ cm} \times 100\% + \frac{0.02\ cm}{2.05\ cm} \times 100\% + \frac{0.01\ cm}{3.1\ cm} \times 100\%[/tex]

= (0.55 + 0.97 + 0.32) × 11.4

= 1.84 × 11.4

= 20.976

Now,

δA = Percent Uncertainty / 100%

     = 20.976 / 100

     = 0.2 cm³

Thus from the above conclusion we can say that Its volume and uncertainty is 11.4 ± 0.2 cm³.

When a 25 g mass is attached to the same spring, the spring is stretched by 2 cm.

According to the question, when a spring is stretched or compressed, the restoring force generated in the spring (towards its mean position) is directly proportional to the length to which it is stretched or compressed.

Mathematically - F = - Kx

Given is a situation in which a stretch of 8 cm is caused by a 100g mass.

From this, we can write -

Mass [m] = 100 g = 0.1 Kg

Displacement [x] = 8 cm = 0.08 m

According to the question -

We will first find the spring constant [K]. Using Hook's law -

F = -Kx

mg = -Kx

K = - mg/x

K = - (0.1 x 9.8) / 0.08

K = - 12.25 N/m

|K| = 12.25 N/m

Now, when mass [M] = 25g = 0.025 Kg, using Hook's law -

|F| = |- kx| = kx

Mg = 12.25x

x = Mg/12.25

x = (0.025 x 9.8)/12.25

x = 0.02

x = 2 cm

Therefore, when a 25 g mass is attached to the same spring, the spring is stretched by 2 cm.

Answer:

1.25 m

Explanation:

Constant Acceleration Equations (SUVAT)

[tex]\boxed{\begin{array}{c}\begin{aligned}v&=u+at\\\\s&=ut+\dfrac{1}{2}at^2\\\\ s&=\left(\dfrac{u+v}{2}\right)t\\\\v^2&=u^2+2as\\\\s&=vt-\dfrac{1}{2}at^2\end{aligned}\end{array}} \quad \boxed{\begin{minipage}{4.6 cm}$s$ = displacement in m\\\\$u$ = initial velocity in ms$^{-1}$\\\\$v$ = final velocity in ms$^{-1}$\\\\$a$ = acceleration in ms$^{-2}$\\\\$t$ = time in s (seconds)\end{minipage}}[/tex]

When using SUVAT, assume the object is modeled as a particle and that acceleration is constant.

Consider the horizontal and vertical motion of the ball separately.

As the ball rolls off the table with a horizontal velocity only, the vertical component of its initial velocity is zero.

Acceleration due to gravity = 10 ms⁻²

As we need to find the vertical displacement of the ball, resolve vertically, taking ↓ as positive:

[tex]u=0 \quad a=10 \quad t=0.5[/tex]

[tex]\begin{aligned}\textsf{Using} \quad s&=ut+\dfrac{1}{2}at^2\\\\s&=(0)(0.5)+\dfrac{1}{2}(10)(0.5)^2\\s&=0+\dfrac{1}{2}(10)(0.25)\\s&=(5)(0.25)\\ \implies s&=1.25 \; \sf m\end{aligned}[/tex]

Therefore, the vertical displacement of the ball is 1.25 m, and so the table is 1.25 m above the floor.

The potential in the parallel-plate capacitor which has a separation of 3.34mm, and each has an area of 10.0 cm² has a potential of 2.52 giga .

Capacitance of a capacitor is a physical property that refers to the ratio of charge store in the parallel plate capacitor to its potential.

Vacuum permittivity, commonly denoted ε₀, is the value of the absolute dielectric permittivity of classical vacuum. It may also be referred to as the permittivity of free space, the electric constant, or the distributed capacitance of the vacuum.

Given:

Charge in the parallel plate capacitor =  670 micro coulomb

Area of the parallel plate capacitor = 10 cm square

Area of separation between plate = 3.34 mm

First we will find the the capacitor in the parallel plate capacitor using its formula.

Capacitance = 2.65 Pico meter

Using the defination of capacitance we have,

Potential of the parallel plate capacitor = capacitance × charge

Potential of the parallel plate capacitor = 670/2.65

Potential of the parallel plate capacitor = 2.52 giga

We are required to find the impulse on the cart

It is given to us that mass of cart is 13kg

It is also given that increase in speed is 1.4 m/s

We are required to find the impulse on the cart

Impulse :

Impulse of a body is defined as change in the momentum of the cart.

Impulse I = m(v-u)/t

Now  (v-u)/t is the change in speed and it is given to us that there is increase in speed and hence it must be positive.

(v-u)/t = 1.4m/s

Therefore,

Impulse of cart is equal to its change in momentum:

Putting the value of mass  in the equation, we get:

I = m(v-u)/t

The maximum value of the resistance is 105,000 Ω

We are given the following properties of the resistor as;

Resistance =  10,000-Ω

Tolerance = 5%

Now, when we say a tolerance of 5%, it means the value of the resistance can only reduce or increase by a maximum of 5%.

Thus;

For a decrease of 5%, we would get the minimum value of the resistance which is;

Minimum value = (100% - 5%) * 10000

Minimum value = 95000 Ω

Then the maximum value of the resistance is;

Maximum Value = (100% + 5%) * 10000

Maximum Value = 105,000 Ω

The electric potential energy of this charge increase as it moves through the battery is 6.84 J.

The power required to move a charge in opposition to an electric field is known as electric potential energy. A charge must be moved through a stronger electric field with more energy, but it also must be moved through a weaker electric field with more energy. The energy gained when an object moves against an electric field is known as the electric potential energy. The electric potential is calculated for any charge by dividing the potential energy by the charge.

Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. This law is important in analyzing problems of static equilibrium, where all forces are balanced, but it also applies to bodies in uniform or accelerated motion.
