Identify the conditions for an elastic collision in a closed system. check all that apply. energy is conserved. velocities may change. momentum is conserved. kinetic energy is conserved. objects stick together after the elastic collision. one object may be stationary before the elastic collision.

In an elastic collision:

When one object is stationary:

Final velocity of object 1:

v₁ = (m₁ - m₂)u₁/(m₁ +m₂)

Final velocity of object 2:

v₂ = (2 m₁ u₁)/(m₁+m₂) =

Thus, conditions for an elastic collision:

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
