Explanation:
My friend this is quite easy.
There is an equation.
The energy is also presumed as heat.
To calculate the heat in a circuit or the energy the equation is H=I(square) RT
Heat= square of current x resistance x time
Here I=5a.
R=2 ohm
T=120s
H= 5x5x2x120=6000J

This unbalanced force causes her to change in direction.
If the forces on an object are unbalanced, this is what happens:
a stationary object starts to move in the direction of the resultant force
a moving object changes speed and/or direction in the direction of the resultant force
