Day 1

1.A gas is compressed isothermally from an initial volume of 3m³ to a final volume of 1m³ .During the compression,the gas releases 300J of heat.If the pressure of gas beginning of the compression is 2 atm,what is the final pressure of the gas?

2.A particle is executing SHM with a frequency of 5Hz and an amplitude of 0.1m.What is the maximum speed of the particle.?

3.Two springs with force constants k1 and K2 are attached in series.A mass m is attached to the combination and displaced from equilibrium position by a distance x .what is the time period of the resulting shm?

4.A simple pendulum of length L is suspended from the ceiling of a train moving with a constant speed v.If the pendulum is displaced by an angle theeta from its equilibrium position,what is the time period of Shm as measured by an observer on the train.

5.A particle of mass is attached to a spring with a force constant k and is executing SHM.If the mass is replaced by mass 2m and the spring constant is doubled what happens to the time period of the motion?
