Essential properties of the medium for wave propagation:
(i) Elasticity: So that particle can return to their mean position, after having been disturbed.
(ii) Inertia : So that molecules can save energy and overshoot their mean position.
(iii)Minimum friction amongst the particles of the medium.
(iv)Uniform density of the medium.
A 9.0-kg crate sits on a level, rough floor. A 61-N force is required just to begin it moving. What is the size of the coefficient of maximum static friction?
If you "bow" a string on a violin you hear a note with a frequency of 1020 Hz. If the length of the string is about 40cm, what is the "wave" on the string? Draw a diagram to show
Write two characteristic features of nuclear force which differentiate it from the Coulomb force.
Illustrate the source of stellar energy. Describe the carbon-nitrogen cycle and proton - proton cycle occurring in stars. Write down a note on ‘Breeder reactor'.
What do you mean by understand by the statement ‘charge is quantized'? The electric lines of force do not intersect. Why?
Calculate the density of sodium metal. The length of the body-centered cubic unit cell is 4.24 A.
Image Formation for Plane Mirrors Not all people who are performance the object within the mirror will sight along the similar geometrical line of sight. The precise direction
A 250 N crate is sitting on a 30 degree inclined plane. The frictional force is larger than the component of the crate's weight parallel to the inclined plane, so that the crate do
It is based on the photovoltaic effect. One of the semiconductor regions is made so thin that the light incident on it reaches the p-n junction and gets absorbed. It changes solar
