Answer:
Explanation:
first mass, m1
second mass, m2
initial velocity of m1 is v1.
initial velocity of m2 is zero.
Let the final velocity of m1 is v' and the final velocity of m2 is v''.
Collision is elastic so the coefficient of restitution is 1.
By using the conservation of momentum
m1 x v1 + m2 x 0 = m1 x v + m2 x v''
m1 v1 = m1 v' + m2 v'' .... (1)
by the formula of coefficient of restitution
v1 = v'' - v' .... (2)
So, v' = v'' - v1 put in equation (1)
m1 v1 = m1 x (v'' - v1) + m2 v''
m1 v1 = m1 v'' - m1 v1 + m2 v''
2 m1 v1 = (m1 + m2) v''
so,
Answer:
C. 1.5 W/m²
Explanation:
= Unpolarized light = 4 W/m²
= Angle with which the polarizer is turned
The polarization of light is given by
The intensity of light after passing through the first polarizer is 1.5 W/m²
