A stone is thrown vertically upward with an initial velocity of 25m/s , calculate time taken to return to the thrower?

no sign of dia of fuel cell

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

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
