It is found that when a liquid is free from the external forces, it always gets the shape of a spherical drop. It is due to, for a needed mass, a sphere has the least field area. It seems that the field of each liquid has usually a tendency to have least field area and in this respect, it functions like a stretched membrane having a force in all directions parallel to the surface. This force in the surface of a liquid is called as surface tension.
A galaxy in the constellation UrsaMajor is receding from the earth at 15,000 km/s. If one of the characteristic wavelengths of the light the galaxy emits is 550 nm, what is the cor

Part A) Infra-Red (IR) Detectors: An IR detector has an impedance of Z= (400+j200) ? . . During design tests the detector current is measured as 4 µA. What is
The loudness of sound depends on: Amplitude of vibration. Area of vibrating body. Distance from the sounding body. Density of the medium.
Displacement related with a wave is given by y (x, t) = 0.1 cos(0.2x-2t). Where x y are in cm and ‘t' in second. Determine the wavelength, amplitude, frequency and velocity.
The points of maximum amplitude are called as antinodes. At ends density and air pressure both are very low.
