According to Hook's law of elasticity, if stress is increased, the ratio of stress to strain
A liquid flows in a tube from left to right as shown in figure. A1 and A2 are the cross-section of the portions of the tube as shown. Then the ratio of speed
v1/v2 will be
The diameter of a ball A is twice of that of B. What will be the ratio of their terminal velocities in water?
Consider two hot bodies B1 and B2 which have temperatures 100°C and 80 °C respectively at t = 0. The temperature of the surroundings is 40 °C . The ratio of the respective rates of cooling R1 and R2 of these two bodies at t = 0 will be
If the degree of freedom of a gas are f, then the ratio of two specific heats CP/CV is given by
