Mary put 30 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 65 mL. What is the
volume of the object?

truck y has a greater velocity than truck x.

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
