Answer:

The Total Momentum before and after collision remains the same.

Explanation:

Note that the balls have the same masses.

A moving cue ball has an initial momentum. After every collision with another stationary ball, the momentum, which is the product of their mass and velocity, of the balls is conserved. This simply means that the total momentum before the collision is the same as the total momentum after the collision.

This also means that the energy must be conserved as well. The balls cannot fling away from each other with more energy than you give them.

Answer:

Total momentum is conserved before and after collusion and it's elastic.

Explanation:

For two colliding balls, the general vector equation for conservation of linear momentum is giving as

Ma*V1a = Ma*V2a + Mb*V2b

Where Ma=mass of que ball = Mb = mass of billiard ball so therefore

V1a= velocity of que ball before impact, V2a = velocity of que ball after impact, V2b = velocity of billiard ball after impact.

So therefore:

V1a = V2a + V2b

A solid box made from a material whose density is rhoS floats with two thirds of its volume submerged in a liquid whose density
jok3333 [9.3K]

Answer:

\frac{\rho_S}{\rho_L} = \frac{2}{3}

Explanation:

density of the solid box material = \rho_s

density of the liquid material = \rho_L

Given that

solid box floats with two thirds of its volume submerged in a liquid

let V be the volume of the box

then,

V\rho_sg= \frac{2V}{3}\rho_L g

⇒\frac{\rho_S}{\rho_L} = \frac{2}{3}

so, the ratio of densities of solid and and the liquid is 2/3

salantis [7]

Answer:

 a= g sinθ

Explanation:

Given that

Angle ,θ = 15° (from the horizontal)

Lets take the mass of the block = m

The acceleration due to gravity = g

The acceleration of the block = a

When block slide down :

The gravitational force on the block =  m g sinθ

By using Newton's second law

F= m a

F=Net force ,a acceleration ,m=mass

m g sinθ =  ma

a= g sinθ

Therefore the acceleration of the block will be g sinθ.
