ball A of mass 5.0 kg moving at 20 meters per second collides with ball B of unknown mass moving at 10. meters per second in the

antiseptic1488 [7]

Answer:The mass of ball B is 10 kg.

Explanation;

Mass of ball A = $M_A=5 kg$

Velocity of the ball A before collision: $U_A=20 m/s$

Velocity of ball A after collision= $V_A=10 m/s$

Mass of ball B= $M_B$

Velocity of the ball B before collision: $U_B=10 m/s$

Velocity of ball B after collision= $V_B=15 m/s$

$M_AV_A+M_BV_B=M_AU_A+M_BU_B$

$5 kg\times 10 m/s+M_B\times 15=5 kg\times 20m/s+M_B\times 10m/s$

$M_B=10kg$

The mass of ball B is 10 kg.

Assume the angular momentum of a diatomic molecule is quantized according to the relation . What are the allowed rotational kine

Komok [63]

Answer:

The answer to this question can be defined as follows:

Explanation:

In the given question, an equation is missing which can be defined as follows:

$I \omega =\sqrt{J(J+1)}h$

solution:

Angular momentum:

$L=I \omega =\sqrt{J(J+1)}h$

Convert Angular momentum in terms of kinetic energy:

$K = \frac{L^2}{2I}$

$= \frac{h^2(J(J+1))}{2I}$
