Draw the free body diagram and label the forces that are appropriate for the situation. 1. A car accelerating down the highway, while the driver has her foot on the gas pedal

an energy transformation flow diagram is shown

where is it ?

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
