Malus' law (E.L. Malus):
The light intensity I of a ray along initial intensity I0 travelling by a polarizer at an angle theta among the polarization of the light ray & the polarization axis of the polarizer is specified by I = I0 cos2 theta.
A proton with a velocity of 3.98 x 10 4 m/s perpendicular to the direction of a magnetic field follows a circular path with a diameter of 4.12 cm. If the mass of a proton is 1.
state and explain pauli''s exclusion principle

For the arrangement shown in Figure find (a) the equivalent capacitance of the circuit, (b) the voltage across QR, and (c) the charge on each capacitor
What is Joule Cycle? Find the efficiency of the Joule cycle, consisting of two isobars and two adiabats. Presume that the heat capacities of the gas C p and C v are constan
INTERFERENCE and DIFFRACTION: INTERFERENCE: The physical effect of super position of waves from two sources vibrating with same frequency and amplitude is called the interfere
Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
Q. If 6.25 X 10 18 electrons flow through a given cross-section in unit time, find the current. Solution: Current I = q / t = ne / t = (6.25 X 10 18X 1.6 X 10 -19) / 1 = 1 A
applications of joule''s law?
