The only way to decrease the inertia of an object is to remove some of its mass. (B)
Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts.

Answer:
36.11 degrees
Explanation:
index of refraction n = sin i/sinr
i is the angle of incidence
r is the angle of refraction
Substitute into the expression
1.39 = sin55/sin(r)
1.39 = 0.8191/sin(r)
sin(r) = 0.8191/1.39
sin(r) = 0.5893
r = arcsin(0.5893)
r = 36.11
hence the angle of refraction of light is 36.11 degrees
<u>Answer</u>: Option C
<em>Pressure is a force shared over an area</em>
<u>Explanation:</u>
Pressure is the result of a force shared over an area. Pressure is explained as the physical force applied on the body.
The applied force is perpendicular to surface of body per unit area.
The symbol used for pressure is P.
<u><em>Formula:</em></u>
P=F/A
<u><em>Where:</em></u>
Pis the pressure,
F is the magnitude of the normal force,
A is area of the surface.
<u><em>The types of Pressures:</em></u>
