To solve this problem we will apply the theorem given in the conservation of energy, by which we have that it is conserved and that in terms of potential and kinetic energy, in their initial moment they must be equal to the final potential and kinetic energy. This is,


Replacing the 5100MJ for satellite as initial potential energy, 4200MJ for initial kinetic energy and 5700MJ for final potential energy we have that



Therefore the final kinetic energy is 3600MJ

Answer:
129.2 C
0.33758239177 mm
Explanation:
n = Number density = 
i = Current = 170 A
t = Time taken = 0.76 s
d = Diameter = 6 mm
Charge is given by

The charge passing throught the motor is 129.2 C
Current density

Drift velocity is given by

Distance traveled

The electron traveled 0.33758239177 mm
but the points are only 25
