Explain why
When we try to close a water tap with our fingers, fast jets of water gush through the openings between our fingers.

The velocity of a particle is towards west at an instant. Its acceleration is not towards west, not towards east, not towards north and not towards south. Give an example of this type of motion.

In which of the gases, liquids or solids is the speed of sound heighest?

Can a ship be moved with the energy of the sea water?

Two gases are at the same temperature, can we conclude that the r.m.s. of gas molecules? Will the velocities be the same? Why?

Which physical quantity gives the area of the velocity-time graph?

How much will be the internal energy change in:

1. Isothermal process.
2. Adiabatic process?

If the magnetic field outside a copper box is suddenly changed, what happens to the magnetic field inside the box? Such low-resistivity metals are used to form enclosures which shield objects inside them against varying magnetic fields.

Write the units of momentum and impulse.
