## Past Paper 10th Class Physics Lahore Board 2014 English Medium Group 2

Physics paper of 10th class Lahore board 2014 of group 1 consists of 12 multiple choice questions, 3 subjective questions having 8 short questions each, 5 long questions and 3 practical questions.  Now there is no more separate practical paper for science subjects. The practical part is included in subjective part of the paper.

Some of the important multiple choice questions are as follows:

• What is an example of shock absorber of the vehicles?
• A large ripple tank with a vibrator working at a frequency of 30 Hz. produces 25 complete waves in a distance of 50 cm. What is the velocity of the wave?
• For a normal person, audible frequency range for sound wave lies between what?
