Sandra moves 14 m in 2 minutes. what is sandra’s average velocity (in m/s)?

Yes but I'm not getting any answer that is listed. What section are you in? Is the motion something I'm unaware of?

Givens

d = 14 m

t = 2 * 60 = 120 seconds

Solution

d = r*t

14 m = r * 120 seconds

r = 14 / 120

r = 0.117 m/s

That m must mean something I'm not seeing.

answer: decibel

explanation:

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
