Mass energy relation - The total energy of a body is the sum of its kinetic energy and rest mass energy. Particle having rest mass zero always move with the velocity of light.
Q. The work function of a metal surface is 1.8 eV. Compute the threshold wavelength. Work function W = hγ o = h C / λ 0 λ 0 = h C / W = 6.626 X 10 -34 X 3 X 10 8
The density of gasoline at 0 degrees C is 0.68 x103 kg/m3 What is the density on a hot day when the temperature is41 degrees C? What is the percentage change (+/-)?
why is the colour of sky blue
(i) Value of vibration of a particle is described as the number of vibrations done by particle in one second. (ii) It is the value of total wavelengths traversed by the wave in
Gravitational field can also be shown by lines of force. This is same in several ways as that of electric lines of forces. With one dissimilarity, electric charges are negative and
The potential difference across a 4 ohm resistor is 20 volts. Assuming that all of the energy dissipated by this resistor is in the form of heat, how many joules of heat are radia
Difference in heights between the pipe and Gage is 5m Density of water is 1000kg/m 3 Acceleration due to gravity 10 m/s 2 Actual Pressure is nothing but the absolute pre
Take the difference among your experimental value and your known value, and divide that difference by your know value. Say you experimentally found the force of gravity to be 8m/s
