Water stored in a dam possesses (d) potential energy and once the water is falling it has kinetic energy.
In optics, Lambert’s cosine law says that the radiant intensity or luminous intensity observed from an ideal diffusely reflecting surface or ideal diffuse radiator is directly proportional to the cosine of the angle θ between the observer’s line of sight and the surface normal.
Rutherford’s scattering experiment proved the presence of nucleus in an atom. Rutherford scattering is the elastic scattering of charged particles by the Coulomb interaction
A shock absorber (in reality, a shock “damper”) is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated.
The time period of a pendulum increases when it will taken to the moon time period will increase because the frequency will decrease on the Moon.
A Newton disc, invented by Isaac Newton, is a disc with seven segments in rainbow colours. When the disc is rotated, the colors fade to white; In this way Isaac Newton demonstrated that white light is a combination of the seven different colours found in a rainbow. A Newton Disc can be created by painting a disc with the seven different colours. A combination of red, green and blue in the circular disc will yield the same result. This is due to the phenomenon called persistence of vision.
The nuclear force is a residual effect of the more fundamental strong force, or strong interaction. The strong interaction is the attractive force that binds the elementary particles called quarks together to form the nucleons themselves. The strong nuclear force has a range of about 1 fm.
Seismology is the study of earthquakes and seismic waves that move through and around the earth.The first kind of body wave is the P wave or primary wave.
Bragg’s spectrometer method is one of the important method for studying crystals using X-rays. The apparatus consists of a X-ray tube from which a narrow b.
