To help you out I'll give you the equations a) s=d ÷t
b) a=vf-vi ÷ t
I think it is D because gas particles move the fastest but if not then it is A
Given two charges,
and
, we can calculate for the electric force with
with k as the Coloumb constant and r as the distance given to be 3 cm or 0.03 m. Plugging this in, we have
Thus, we have F = 10 N.
Answer: 10N
Answer:
The energy ratio is
Explanation:
The kinetic energy of the 20mph object is
,
and the kinetic of the same abject at 5mph is
therefore, the ratio of to is
Thus, the energy ratio is .
