A 500g cart moving at 0.25 m/s collides and sticks to a stationary 750g cart. How fast do the two carts move after the collision? Sketch a diagram and use vectors to represent the velocities.

Acricket ball of 70g moving with a velocity of 0.5 m/s is stopped by a player in 0.5s what is the force applied to stop the ball

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
