Puck 1 (1 kg) travels with velocity 20 m/s to the right when it collides with puck 2 (1 kg) which is initially at rest. After th
Burka [1]

Answer:

Explanation:

Parameters given:

Mass of Puck 1, m = 1 kg

Mass of Puck 2, M = 1 kg

Initial velocity of Puck 1, u = 20 m/s

Initial velocity of Puck 2, U = 0 m/s

Final velocity of Puck 1, v = 5 m/s

Since we are told that momentum is conserved, we apply the principle of conservation of momentum:

Total initial momentum of the system = Total final momentum of the system

mu + MU = mv + MV

(1 * 20) + (1 * 0) = (1 * 5) + (1 * V)

20 = 5 + V

V = 20 - 5 = 15 m/s

Puck 2 moves with a velocity of 15 m/s

Human laws are more important than natural laws for human why?
Vika [28.1K]

En el presente ensayo se hace una reseña de las críticas que ha recibido la teoría de la ley natural, originalmente propuesta por Germain Grisez y posteriormente desarrollada por otros filósofos del derecho, como John Finnis, Joseph Boyle, William May y Patrick Lee. Los objetivos del autor son demostrar, en primer lugar, que contrariamente a lo que sus críticos afirman, la teoría de la ley natural propuesta por Grisez no excluye el supuesto de que el bien humano básico o las normas morales están basadas en la naturaleza humana o tienen conexión con ella; y en segundo lugar, que Grisez y sus seguidores están en lo correcto al mantener que nuestro conocimiento del bien humano básico y de las normas morales no necesita ni puede ser lógicamente deducido o inferido o derivado de los hechos de la naturaleza humana.

What does the Kinetic Theory Model state?
amid [387]

Answer:

B. particles in solid objects do not move

Explanation:

The kinetic theory model states that matter is made up of particles that are constantly moving but the movement of particles depends on whether the substance exists in the solid, liquid, or gaseous state.

So, according to the Kinetic Theory Model state, particles in solid objects do not move as all the particles in solids are closely packed.

Hence, the correct option is "B”.
