A person weighing 645 N climbs up a ladder to a height of 4.55 m. 1. What work does the person do?
2. What is the increase in gravitational potential energy?
3. Where does the energy come from to cause this increase in ?

i don't know that i agree with that but what's the question ?

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch

360seconds i 1 hr

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
