Auniform electric field of magnitude 300 v/m is directed in the negative x-direction. a 20 µc, 10 ? g particle moves from the origin to the point (x, y) = (20 cm, 50 cm).
(a) through what electric potential difference did the particle move?

(b) what was the work done on this particle?

(c) if the particle's speed was 600 m/s at the origin, what is it's speed at the point (x, y) = (20 cm, 50 cm)?

the cellphone, they would then know if the killer would have contacted them or always hated them. or if it was a breakup. but if that is not the case, then it would be the clothing. to put in a bullet, it would have to be put in by hands. hands have finger prints which, would have giving you the answer of who done it.

explanation:

this is a good question! i'll do some research and come back when i have the answer!

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
