Q # 1
Can a converging lens be made to diverge light if it is placed intoa liquid? What If? How about a converging mirror? Q#2 a) Give an example where no heat is transferred to or from asystem but the temperature of the system changes. b) Why is it wrong to think of heat as a form of storedenergy? Q#3 Calculate the K.E of an electron moving with a velocity of0.98 times the velocity of light in the laboratory system. Q#4 At what speed is a particle moving if the mass is equal tothree times its rest mass? Q # 1

Explanation / Answer

(3) .  The K.E of an electron moving with a velocityof 0.98 times the velocity of light in the laboratory systemis               K.E = m c 2 - m o c 2 where m o = rest mass of electron = 9.1 * 10-31 kg            c= speed of light = 3 * 10 8 m / s            m= m o / [ 1 - ( v 2 / c 2 )] Substitue values weget answer where m o = rest mass of electron = 9.1 * 10-31 kg            c= speed of light = 3 * 10 8 m / s            m= m o / [ 1 - ( v 2 / c 2 )] Substitue values weget answer
