Two objects of masses 50 g and 100 g are moving along the same line and direction with velocities of 5 m/s and 10 m/s respectively. They collide and after collision, the second object moves at a velocity of 8 m/s. Determine
the velocity of the second object.

Which feature of a heating curve indicates a change ofn state

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

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? ?
