I would say Book B.
Gravitational Potential Energy is mass * gravity * height.
Gravity is same for the same, it's constant.
Book C is the lowest, so it has less height.
And Book B is clearly the more massive of Book A and Book B, which are the same height.
Book B
The average current passing through a device is given by:
I = Q/Δt
I is the average current
Q is the amount of charge that has passed through the device
Δt is the amount of elapsed time
Given values:
Q = 4.00C
Δt = 4.00hr = 14400s
Plug in the values and solve for I:
I = 4.00/14400
I = 0.000277777778A
I = 0.278mA
Answer:
this depends on religion

Answer:
Explanation:
The distance of Earth from the Sun is and of Mars from the Sun is . Let assume that both planets have circular orbits. The centripetal accelaration can be found by using the following expression:
Since planet has translation at constant speed, this formula is applied to compute corresponding speeds:
Earth:
Mars:
Now, centripetal accelarations can be found:
Earth:
Mars:
The ratio of Earth's centripetal acceleration to Mars's centripetal acceleration is:
