Abox experiencing a gravitational force of 600 n is being pulled to the right with force of 250 n. a 25 n frictional force acts on the box as it moves to the right.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

b. a lightning bug, plug of grass, and a worm

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
