The angle of reflection equals the angle of Incidence
Explanation:
The Law Of Reflection
Answer:
42km/h
Explanation:
Change in km/ Change in time
1.4 x 100
0.033 x100
140km/3.3
= 42.4242 --> 42km/h

Avg acceleration; under constant acceleration condition only; = Vf-Vi/time
a=Vf-Vi/time=(15m/s-6m/s)/(3s)=
(9m/s)/(3s)=3m/s^2
Hope this helps. Thanks.
D. it is decreased by a factor of 9.
Force = kqq ÷ r^2
The distance is squared so if it is increased or decreased by any factor, then it must be squared too. Because the distance is on the bottom of the equation, you divide the force by the increasing or decreasing factor.
