Kinetic theory explains the behavior

A 14.5 kg mass, fastened to the end of a steel wire of unstretched length 1.0 m, is whirled in a vertical circle with an angular velocity of 2 rev/s at the bottom of the circle. The cross-sectional area of the wire is 0.065 cm². Calculate the elongation of the wire when the mass is at the lowest point of its path.

Two bullets A and B are fired horizontally with speed v and 2v respectively.which of the following is true

The displacement of a damped harmonic oscillator is given by:

x(t) = e^-0.1t cos (10πt + φ). Hence, t is in seconds.

The time taken for its amplitude of vibration to drop to half of its initial value is close to:

1 mole of a monoatomic gas is mixed with 3 moles of a diatomic gas. What is the molecular specific heat of the mixture at constant volume?

The average distance a molecule can travel without colliding is called the

Value of gas constant, R for one mole of a gas is independent of the

According to kinetic theory of gases, 0K is that temperature at which for an ideal gas

Four moles of an ideal diatomic gas is heated at constant volume from 20° C to 30° C. The molar specific heat of the gas at constant pressure (Cp) is 30.3 Jmol^-1K^-1 and the universal gas constant (R) is 8.3 Jmol^-1K^-1. The increase in internal energy of the gas is

Three moles of an ideal monoatomic gas is initially in the state A shown in the adjoining pressure-temperature graph. It is taken to state B without changing its pressure. If R is the universal gas constant, the work done by the gas in this process is
