A gas is initially at a pressure of $100kPa$ and its volume is $2.0m^3$. Its pressure is kept constant and the volume is changed from $2.0m^3$ to $2.5m^3$​​​​​​​. Its volume is now kept constant and the pressure is increased from $100kPa$ to $200kPa$. The gas is brought back to its initial state, the pressure varying linearly with its volume.

  2. How much heat was supplied or extracted?
Two friends A and B (each weighing $40kg$) are sitting on a frictionless platform some distance d apart. A rolls a ball of mass $4kg$ on the platform towards B which B catches. Then B rolls the ball towards A and A catches it. The ball keeps on moving back and forth between A and B. The ball has a fixed speed of 5m/s on the platform.
  1. Find the speed of A after he rolls the ball for the first time.
  2. Find the speed of A after he catches the ball for the first time.
  3. Find the speeds of A and B after the ball has made 5 round trips and is held by A.
  4. How many times can A roll the ball?
  5. Where is the centre of mass of the system ''A + B + ball'' at the end of the $n^{th}$ trip?
The height y and the distance x along the horizontal plane of a projectile on a certain plane (with no atmosphere) are given by $x = (6t)$ metre; $y = (8t - 5r^2)$ metre. where t is in seconds. What is the velocity with which the projectile is projected?
A resistance thermometer reads R =$20.0\Omega$, $27.5\Omega$, and $50.0\Omega$ at the ice point $(0^\circ C)$, the steam point $(100^\circ C)$ and the zinc point $(420^\circ C)$ respectively. Assuming that the resistance varies with temperature as$\text{R}_\theta=\text{R}_0(1+\alpha\theta+\beta\theta^2)$, find the values of $\text{R}_0,$ $\alpha \ \text{and}\ \beta.$ Here $\theta$ represents the temperature on Celsius scale.
