Question

Look out! There is a long, straight wire coming out of the page below with current flowing directly toward you! Draw the magnetic field from the current carrying wire. True or false, circle one for each statement: a. A heavy object falls faster than a light object when there is no air resistance. True False Momentum is conserved in an in-elastic collision. True False The angular momentum of the ball travelling in circular motion is L = %" mass" velocity" radius of circular motion. True False The reason we put a door handle on the opposite edge of the door from the hinges is that this decreases the torque needed to open the door. True False Physics 151 in the summer time, is a very intense course. True False

Explanation / Answer

(a) True, because the mass is depends upon timeperiod

(b) True because the momentum is conserved only

(c) true because angular momentum =I*W=1/2mr^2*w=1/2*m*r*v

(d) True because torque = radius *applied force

(e) True
