A gas with a ratio of specific heats, \( \gamma = \frac{4}{3} \), is heated isobarically. The percentage of the given heat used in external work done is

The oxygen gas of 5 moles is heated at constant pressure from 300 K to 320 K. The amount of energy spent during this expansion is 
(For oxygen \( C_p = 7 \, {Cal/mol} \cdot \degree C \), \( C_v = 5 \, {Cal/mol} \cdot \degree C \)) 
 

In which of the following thermodynamic processes, the total amount of heat supplied to the system is only used to rise the temperature?
A U-tube is partially filled with water. Oil which does not mix with water is next poured into one side of the U-tube until entire water rises by 25 cm on the other side. If the density of oil is 0.8 g cm\(^{-3}\), the oil level will stand higher than the water level by:
The Poisson’s ratio of a material is 0.4. If the force is applied to a wire of this material, there is a decrease of cross-sectional area by 2%. The percentage increase in its length is:
The gravitational field due to a mass distribution is \( E = \frac{K}{x^3} \) along x-direction (K is a constant). Taking the gravitational potential to be zero at infinity, its value at a distance \( x \) is:
A torque of 10 Nm is applied on a wheel having angular momentum of 2 kg m\(^2\) s\(^{-1}\). The angular momentum of the wheel after 4 s is:
A solid flywheel of mass 20 kg and radius 100 mm revolves at 600 revolutions per minute. If the coefficient of friction is 0.1 and to stop the flywheel in 3.14 s, the force to be applied against is approximately:
A ball strikes a horizontal floor at 45°. If 25% of its kinetic energy is lost in the collision, then the coefficient of restitution is:
An elevator can carry a maximum load of 2000 kg (elevator + passengers) and is moving up with a constant speed of 9 km/h. If the frictional force opposing the motion is \( 5 \times 10^3 \) N, the minimum power delivered by the motor to the elevator is (acceleration due to gravity = 10 ms\(^2\))
A body slides down an inclined plane of angle of inclination 30\(^\circ\) with a constant velocity of 10 ms\(^{-1}\). If the body is pushed up the same plane with a velocity of 20 ms\(^{-1}\), the distance moved by the body before coming to rest is (acceleration due to gravity = 10 ms\(^2\))
A body is projected horizontally from the top of a tall tower. At a time of 3.5 s from the projection, the horizontal and vertical displacements of the body are equal. The velocity of projection of the body is (acceleration due to gravity = 10 ms\(^2\))

The relation between velocity \( V \) (in ms\(^{-1}\)) and the displacement \( x \) (in meters) of a particle in motion is \( 2V = \sqrt{37 + 32x} \). 
The acceleration of the particle is
