Sample Response: Yes, the law of conservation of momentum is satisfied. The total momentum before the collision is 1.5 kg • m/s and the total momentum after the collision is 1.5 kg • m/s. The momentum before and after the collision is the same.

Answer: yes, the law of conservation of momentum remains conserved always in a closed system.

Explanation:

Law of conservation of momentum states that initial momentum of the components in a closed system is equal to final momentum of the components. Thus, the total momentum remains constant i.e. conserved. The law of conservation of momentum hold true in all conditions - be it elastic collision or inelastic collision.

When two balls collide on pool table, the law of conservation of momentum is satisfied.

What happens to light when it strikes the inside surface of a smooth, curved mirror? It bounces in random directions. It bounces
kotykmax [81]
This is a concave mirror you're talking about, so all of the points are going to converge to a single focal point. Therefore the answer would be that it bounces back toward a single spot

Describe the relationship between joules, meters, and newtons
Naily [24]
Newton is a unit of force. Joules is an amount of work which is equal to the force times distance, or newton meters. So the product of newtons and meters makes joules.

A clear sheet of polaroid is placed on top of a similar sheet so that their polarizing axes make an angle of 30° with each other
xxMikexx [17]

Answer:

\dfrac{I}{I_0}=\dfrac{3}{8}

Explanation:

Given that

Angle ,θ = 30°

From Malus law,Intensity given as

I=\dfrac{I_0}{2}cos^2\theta

Io=Intensity of unpolarized light

I=Intensity of emerging light

Now by putting the value of angle

I=\dfrac{I_0}{2}cos^2\theta

I=\dfrac{I_0}{2}cos^230^{\circ}

We know that

cos30^{\circ}=\dfrac{\sqrt{3}}{2}

I=\dfrac{I_0}{2}\times \dfrac{3}{4}

\dfrac{I}{I_0}=\dfrac{3}{8}

Therefore ratio will be \dfrac{3}{8}
