Two identical 0.25kg balls are involved in a head on elastic collision. Ball A is initially traveling at 3.5 M/S and Ball B is initially at rest. A) Describe what will happen when the balls collide.

B) Calculate the momentum of Ball A before the collision.

C) Calculate the total momentum after the collision.

D) Determine the velocity of each Ball after the collision.

What would be the result of an alpha particle coming into a magnetic field? a) the alpha particle will stop moving. b) the alpha particle will reverse its direction. c) the alpha particle will be deflected in a curve path. d) the alpha particle will continue to travel in a straight line.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
