Quien me ayuda en una tarea de matemáticas de una figura geométrica que no se cómo se llama​

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Agraduated cylinder contains 63.0 ml of water. a piece of gold, which has a density of 19.3 g/ cm3, is added to the water and the volume goes up to 64.5 ml. calculate the mass in grams of the gold that was added to the water. explain how you got your answer.

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
