A shell is fired from a cannon with a velocity V at an angle $\theta$ with the horizontal direction. At the highest point in its path, it explodes into two pieces of equal masses. One of the pieces retraces its path to the cannon. The speed of the other piece immediately after the explosion is:
  1. $\text{3V}\cos\theta$
  2. $2\text{V}\cos\theta$
  3. $\frac{3}{2}\text{V}\cos\theta$
  4. $\text{V}\cos\theta$

As the temperature of a conductor increases, its resistivity and conductivity change. The ratio of resistivity to conductivity:
A wall clock uses a vertical spring-mass system to measure the time. Each time the mass reaches an extreme position, the clock advances by a second. The clock gives correct time at the equator. If the clock is taken to the poles it will:

  2. Run fast.
  3. Stop working.
  4. Give correct time.

Three transparent media of refractive indices $\mu_1,\mu_2$ and $\mu_3.$ A point object $O$ is placed in the medium $\mu_2.$ If the entire medium on the right of the spherical surface has refractive index $\mu_1,$ the image forms at $O\ '$. If this entire medium has refractive index $\mu_3,$ the image forms at $O"$. In the situation shown:
