The current is 3.33A, the resistance is 36.03 Ohm, and the peak voltage is 169.68V.

Given information:

The power rating of the resistive element (P) = 400 W

Voltage supplied by the outlet (V) = 120 VAC (RMS)

a) To find the current flowing through the element, the formula:

Power (P) = Voltage (V) × Current (I)

Current (I) = Power (P) / Voltage (V)

Substituting the given values:

Current (I) = 400 W / 120 VAC

= 3.33 A

b) To find the resistance of the element, Ohm's Law can be used :

Resistance (R) = Voltage (V) / Current (I)

Resistance (R) = 120 VAC / 3.33A

= 36.03 Ohm

c) To find the peak voltage, it is required to convert the RMS voltage to peak voltage. For an AC voltage, the relationship between RMS voltage (\(V_{rms\)) and peak voltage (\(V_{peak\)) is given by:

\(V_{peak} = V_{rms} \times \sqrt2\)

Substituting the given RMS voltage:

Peak voltage  = \(120 \times \sqrt2\)

= 169.68 V

The distance traveled by the Earth after 6 months or 1 year is equal to the circumference of its orbit (2πR), and the displacement is zero for both time periods. To calculate the distance traveled and the displacement of the Earth after a certain time period, we can use the formula:

Distance = Speed * Time In this case, the speed of the Earth's revolution around the Sun is constant, so we can use the average distance between the Sun and the Earth (R) as the value for speed. Distance traveled after 6 months: The time period is 6 months, which is equal to 0.5 years.

Distance = R * Time

Distance = (1.5 * 10^8 km) * (0.5 years)

Distance = 7.5 * 10^7 km Displacement after 6 months: Displacement refers to the change in position, so we need to consider the direction as well. After 6 months, the Earth would have completed half of its revolution around the Sun, so the displacement is zero. This is because the Earth ends up in the same position relative to the Sun after half a year. Distance traveled after 1 year:

The time period is 1 year.

Distance = R * Time

Distance = (1.5 * 10^8 km) * (1 year)

Distance = 1.5 * 10^8 km

Displacement after 1 year: Similar to the previous case, the Earth completes one full revolution around the Sun in one year, so the displacement is zero. The Earth returns to its initial position after a complete revolution. Therefore, the distance traveled by the Earth after 6 months or 1 year is equal to the circumference of its orbit (2πR), and the displacement is zero for both time periods.

The coin should be placed 6 cm below the end of the ramp.

We can use the concept of time of flight. The time of flight is the time it takes for an object to travel from one point to another under the influence of gravity

An equation is a mathematical statement that is made up of two expressions connected by an equal sign

The time of flight can be calculated using the following equation:

T = 2 * √(2*d / g)

Where:

T is the time of flight

d is the vertical distance the object falls

g is the acceleration due to gravity (approximately 9.8 m/s^2)

We know that the distance between the photogates is 30 cm and the time it takes for the ball to pass through is 0.20 s. We can use this information to calculate the vertical distance the ball falls:

d = (1/2) * g * T^2

d = (1/2) * 9.8 * (0.20)^2

d = 0.98 m

Now we can use this distance to calculate the vertical distance from the end of the ramp to where the coin should be placed:

Vertical distance from end of ramp to coin = 92 cm - 0.98 m

= 92 cm - 98 cm

= -6 cm

So, the coin should be placed 6 cm below the end of the ramp.

Answer:

Around \(1.4\) solar mass.

Explanation:

In a white dwarf, electron degeneracy prevents the star from collapsing into itself. However, if the mass of the star exceeds the Chandrasekhar Limit, gravity would overcome electron degeneracy and star would collapse further.

The value of the Chandrasekhar Limit is approximately \(1.4\; M_{\odot}\) (\(1.4\) times the mass of the sun.) While this mass is the maximum possible mass of a stable white dwarf, the original mass of the star that formed this white dwarf tends to be much greater.

A particle moving at speed 0.32 c has momentum P₀. the speed of the particle is increased to 0.72 c then its momentum would be 2.25P₀.

It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.

Mathematically the formula of the momentum is

P = mv

where P is the momentum of the particle

m is the mass of the particle

v is the velocity by which the particle is moving

As given in the question a particle moving at speed 0.32 c has momentum P₀. the speed of the particle is increased to 0.72 c

by using the formula of the momentum and substituting the values of the velocity

P =mv

As mentioned in the question when the particle is moving with 0.32c velocity it has a momentum of P₀

P₀ = m*(0.32c)

If the speed of the particle is increased to 0.72 c the momentum would be

P=m*(0.72c)

by dividing the second equation from the first one

P₀/P = 0.32c/0.72c

P₀/P = 0.44

P =2.25P₀

Thus, the increased momentum of the particle would be 2.25P₀

The factors that can change the pattern observed on a screen during Young's double-slit experiment are given below:1. Width of the slit. 2. Distance between slits. 3. Distance between slits and screen. 4. Wavelength of the incident light. 5. Refractive index of the medium.

The factors that can change the pattern observed on a screen during Young's double-slit experiment are given below:

1. Width of the slit. The width of the slit can influence the diffraction pattern that is observed on a screen. When the width of the slit decreases, the central maximum of the diffraction pattern becomes broader, and the intensity of the secondary maxima reduces.

2. Distance between slits. The distance between the slits in the double-slit experiment also affects the pattern on the screen. The distance between the slits is equal to the spacing between the maxima. If the spacing between the slits decreases, the distance between the maxima decreases, and vice versa.

3. Distance between slits and screen. The distance between the slits and the screen is also a factor that can affect the diffraction pattern. When the distance increases, the spacing between the maxima becomes wider, and the intensity of the maxima decreases.

4. Wavelength of the incident light. The wavelength of the incident light is another factor that affects the diffraction pattern on the screen. When the wavelength increases, the spacing between the maxima increases, and vice versa.

5. Refractive index of the medium. The refractive index of the medium in which the light travels can also influence the diffraction pattern observed on a screen.

When the refractive index of the medium changes, the position of the maxima changes as well. These are the factors that can change the pattern observed on a screen during Young's double-slit experiment.

(a) The maximum tensile stress in the standard weight steel pipe is determined to be 16,000 psi.

(b) Assuming an extra-strong pipe, the maximum tensile stress is calculated to be 20,000 psi.

(a) To calculate the maximum tensile stress in the standard weight steel pipe, we need to consider the internal pressure acting on the pipe. The internal pressure is given as 400 psi. The maximum tensile stress can be determined using the formula:

Maximum Tensile Stress = (Internal Pressure * Outside Diameter) / (2 * Wall Thickness)

Substituting the given values into the formula, we get:

Maximum Tensile Stress = (400 psi * 12.75 in.) / (2 * 0.375 in.) = 16,000 psi

Therefore, the maximum tensile stress in the standard weight steel pipe is 16,000 psi.

(b) Similarly, for the extra-strong pipe, we use the same formula but with the given dimensions for the outside diameter and wall thickness. Substituting the values, we get:

Maximum Tensile Stress = (400 psi * 12.75 in.) / (2 * 0.5 in.) = 20,000 psi

Therefore, for the extra-strong pipe, the maximum tensile stress is 20,000 psi.

The thermal efficiency of the given heat engine is 47%, while the thermal efficiency of the corresponding Carnot cycle is 58.24%. The heat engine falls short of the Carnot efficiency, suggesting inefficiencies or design limitations.

(a) To determine the thermal efficiency of the given heat engine, we can use the formula:

Thermal Efficiency = (Net Work Output / Heat Input) * 100

The net work output can be calculated by subtracting the heat rejected from the heat input:

Net Work Output = Heat Input - Heat Rejected

Given:

Heat Input = 500 kW

Heat Rejected = 265 kW

Substituting these values into the formula, we have:

Net Work Output = 500 kW - 265 kW = 235 kW

Now, we can calculate the thermal efficiency:

Thermal Efficiency = (235 kW / 500 kW) * 100 = 47%

Therefore, the thermal efficiency of this cycle is 47%.

(b) The Carnot cycle is an idealized reversible heat engine that operates between two heat reservoirs. Its thermal efficiency can be determined using the formula:

Thermal Efficiency Carnot = 1 - (T_low / T_high)

Given:

T_low = 50°C + 273.15 = 323.15 K

T_high = 500°C + 273.15 = 773.15 K

Substituting these values into the formula, we have:

Thermal Efficiency Carnot = 1 - (323.15 K / 773.15 K) ≈ 0.5824 (58.24%)

Therefore, the thermal efficiency of the corresponding Carnot cycle is approximately 58.24%.

(c) Comparing the thermal efficiency of the given heat engine (47%) with the thermal efficiency of the Carnot cycle (58.24%), we can conclude that the heat engine is less efficient than the corresponding Carnot cycle. In theory, the maximum efficiency any heat engine can achieve is the Carnot efficiency when operating between the same temperature limits. The given heat engine falls short of the Carnot efficiency, indicating that it is not operating at the maximum possible efficiency.

This comparison suggests that the given heat engine may not be feasible or ideal. It could be due to factors such as irreversibilities, inefficiencies in the conversion of heat to work, or losses in the system. Improving the design or addressing these inefficiencies would be necessary to approach the ideal efficiency of the Carnot cycle.

A passenger weighing 500N is inside an elevator weighing 24500 N that rises 30 m every minute is 12500 W (12.5 kW).

What is Power?

Power is the amount of work that is done per unit of time. It can be associated with the speed of a change of energy within a system, or the time it takes to perform a job.

There are different types of power,

Mechanical power: is that work performed by an individual or a machine in a certain period of time.

Electric power: which is the result of the multiplication of the potential difference between the ends of a load and the current flowing there.

P= W/t

Where, P- Power,

W- Work

T- Time

The total weight of the passenger + elevator is

Fg = 500+24500

    = 25000

The total work done to rise the elevator + passenger is equal to the product between the total weight and the distance covered during the trip (d = 30 m):

W = Fgd

   = 25000×30

   =7,50,000 J.

The power needed for the trip is equal to the ratio between the work done (W) and the time taken (t):

P = W/t

Since the time taken is t = 1 min = 60 s, the power needed is

P = 750000 / 60

   = 12,500 W

P = 12.5 kW

Thus, Power was calculated as P = 12.5 kW.
