Answer:
Force = mass * acceleration
F = m*a
Hope this helps
<span>Velocity is a vector and it has both speed and direction. It takes a force to change direction just as it does to change speed</span>. In order to have a constant velocity the object must maintain a constant direction and speed. Hope this answers the questions. Have a nice day.
Answer:
<h3>1.502</h3>
Explanation:
Using the snell's law refraction to solve this problem;
According to the law, the ratio of the sine of incidence to the sine of refraction is a constant for any given pair of medium. Mathematically;

n is the refractive index of benzene
i is the angle of incidence = 43°
r is the angle of refraction = 27°
Get the index of refraction of benzene;

Hence the index of refraction of benzene is 1.502

Answer:
positive direction with a changing velocity. An object which moves in the positive direction has a positive velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration
