Answer:
20 Watt
Explanation:
Applying
P = V²/R................... Equation 1
Where V = Voltage, P = Power, R = resistance
From the question,
Given: V = 100V, R = 500 ohms
Substitute these values into equation 1
P = (100²)/500
P = 10000/500
P = 20 Watt.
Hence the power required to light the bulb is 20 W
The input force will increase too because the more the ramp is increasing the more force is being put on the object going down the ramp... hope this helps ^-^
To solve this problem we will apply Newton's second law, which indicates that the force is equivalent to the product between mass and acceleration, so

Here,
F= Force
m = Mass
a = Acceleration
Rearranging to find the mass we have,

The value of the acceleration is


Replacing to find the mass,



Now in ponds this value is


Therefore the mass of the spacecraft is 52.8lb
