Answer:
Explanation:
From the question, acceleration from in 10 seconds.
Acceleration function can be written as:-
From the acceleration equation, we can obtain the velocity equation:
We calculate velocity after 10sec from the above v(t) as .
To obtain distance travelled after 10 seconds:-
Therefore 200m is for 10seconds, and next 200m at 30m/s
Total time=
Answer:
it will take for the sphere to increase in potential by 1500 V, 503.71 s.
Explanation:
The charge on the sphere after t seconds is:
q = (1.0000049 - 1.0000000) t = 0.0000049 t
The voltage on the surface is
V = k * = k 0.0000049 t / R
solve for t
t = (R*V) / (0.0000049 k) = (0.12 * 1500) / (0.0000049 * ) = 503.71 s
