Aset of charged plates have an area of 8.22 x 10 ^ -4 m*2 and separation 2.42*10^-5 the plates are charged with 5.24 x 10^- 8 what is the potential difference between the plates?

it becomes positively charged by charging it

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

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

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
