In linear motion, the energy is given by 1⁄₂mv². Similarly, in rotational motion, the rotational energy is given by

1. 1/2 × I × Ω; where I: moment of inertia of the body, Ω: angular velocity
2. 1/2 × I² × Ω; where I: moment of inertia of the body, Ω: angular velocity
3. 1/2 × I × Ω²; where I: moment of inertia of the body, Ω: angular velocity
4. 1/2 × I² × Ω²; where I: moment of inertia of the body, Ω: angular velocity

Boyle's law states that

1. pressure of a gas is inversely proportional to its volume i.e. P × V = constant
2. pressure of a gas is directly proportional to its volume i.e. P⁄V = constant
3. pressure of a gas is inversely proportional to the square of its volume i.e. P × V² = constant
4. pressure of a gas is directly proportional to the square of its volume i.e. P ⁄ V² = constant

Isothermal bulk modulus is equal to

1. Υ × P; where Υ: the ratio of the specific heat capacities of the gas, P: pressure
2. Pressure
3. The ratio of the specific heat capacities of the gas
4. Υ ⁄ P; where Υ: the ratio of the specific heat capacities of the gas, P: pressure

Adiabatic bulk modulus is equal to:

1. Υ × P; where Υ: the ratio of the specific heat capacities of the gas, P: pressure
2. Pressure
3. The ratio of the specific heat capacities of the gas
4. Υ ⁄ P; where Υ: the ratio of the specific heat capacities of the gas, P: pressure

Bernoulli's principle shows that, at points in a moving fluid where the potential energy change is very small

1. the pressure is low where the velocity is low and similarly, the pressure is high where the velocity is high
2. the pressure is low where the velocity is high and conversely, the pressure is high where the velocity is low
3. pressure becomes independent of the velocity of the moving fluid
4. pressure remain independent of the speed of the stationary fluid
