Define Lenzs law
Lenz's law (H.F. Lenz; 1835): The induced electric current always flows in such a direction that it resists the change generating it.
Ultraviolet catastrophe: It is the shortcoming of Rayleigh-Jeans formula that attempted to explain the radiance of a blackbody at different frequencies of the electromagnetic spectrum. This was clearly wrong since as the frequency rose, the radiance r
The voltage v mV in a circuit is given by: v = 20 sin (200 Πt - 0.7854) where t is the time in seconds (a) State the amplitude, frequency, period and phase angle of v.(b) Determine the initial voltage.(c) Determin
What do you mean by the term information in physics?
Boltzmann constant: k (L. Boltzmann) - The constant that explains the relationship between kinetic energy and temperature for molecules in an ideal gas. This is equivalent to the 1.380 622 x 10-23 J/K.
Lyman series: The sequence that explains the emission spectrum of hydrogen whenever electrons are jumping to the ground state. Each and every line is in the ultraviolet.
Briefly describe the reason why it takes longer to heat a bucket of water than the cup of water?
Causality principle: The principle which cause must always precede effect. More properly, when an event A ("the cause") somehow persuades an event B ("the effect") that take
