Answer:
Explanation:
Given
The voltage of the battery is
Current through the battery is
(a) Power is the product of voltage and current
Power dissipates is given by
(b) Energy delivered
Answer:
a) 8.85 kJ
b) 7.85 kJ
c) 6.85 kJ
Explanation:
we will use the energy conservation theorem for all of the stages
for stage 1:
the initial velocity and the potential gravitational energy at the bottom is zero:
for stage 2:
the velocity is constant so there is no change in the kinetic energy, so there is change only on the potential gravitational energy:
for stage 3:
there is a change for both, gravitational and kinetic energy so:
