problems involving elastic and inelastic collisions in one dimension

Robert was asked to make a lid for a cylindrical tank open at one end. The lateral surface area of the tank is given as 2622 m 2 with a height of 23 m. Identify the net diagram which shows the correct dimensions of the tank with a lid. [Take π = 3.] => Figure 1 or F..

Let us study another type of energy, called the potential energy. Potential energy is the energy that can be associated with the configuration (or arrangement) of a system of objects that exert forces on one another. If the configuration of the system changes, then the potential energy o..

All the molecules of a gas are identical with respect to their shape and mass. The molecules of different gases are different. The gas molecules behave as rigid, elastic and smooth spheres. The size of gas molecules is very less when compared to the intermolecular distance between..

The word 'Kinetic' means due to motion. The Kinetic Theory of Gases is based on the idea that gases consist of atoms and molecules moving ceaselessly and randomly with all possible velocities in all directions. Each of these gas particles has certain amount of kinetic energy that depends upon its t..

The flash of lightning due to collision of clouds is seen much before the thunder, although both occur simultaneously. This happens because the velocity of light is greater than the velocity of sound. The speed of sound depends on (1) elasticity and (2) density of the ..

All gases are made up of large number of minute particles called molecules. Large distances separate the molecules so that the actual volume of the molecules is negligible as compared to the total volume of the gas. The molecules are in a state of constant rapid motion in all directions, co..

From Newton's third law of motion we know that whenever a force is applied on a body there will be an equal and opposite reaction. Action and reaction forces result in change in velocities of both the bodies which in turn change the momenta of these bodies. In an elastic collision..

These observations explained that there was a coulomb interaction between a particles and electron. As a particles were 7000 times more massive than electrons, a strong force is needed to deflect them through large angles. Therefore the entire +ve charge of the gold foil was concentrated at th..

.e., a to and fro motion. A given point in the path is crossed by the body in opposite directions at regular intervals. This is called oscillatory motion. All oscillatory motions are periodic but not all periodic motions are oscillatory. On observing an oscillating system, like a loaded spring, ..

The value of a physical quantity can be obtained in some other system, when its value in one system is given using the method of dimensional analysis. Measure of a physical quantity is given by X = nu, u - size of unit, n - numerical value of physical quantity for the chosen unit. Let u h..
