It having of a Cu plate coated with a thin layer of cuprous oxide (Cu2O). On this plate is laid a semi transparent thin film of silver.
When light fall, the electrons emitted from the layer of Cu2O and move towards the silver layer. Then the silver layer changes into negatively charged and copper plate become positively charged. A potential dissimilarity is set up among these two and current is set up in the external resistance.
Explain moment of inertia Moment of inertia is the term used to calculate or quantify the amount of mass located at an object's extremities. For instance if all the mass of an
The photon fluence rate is 10 7 photons mm -2 sec -1 for a beam of γ rays. One fourth of the photons have energies of 100 keV, one half have energies of 80 keV and the remaining
Molecules: Let us take a piece of matter, for example, a drop of water and see what happens when it is sub-divided into smaller and smaller portions. The drop is first cut
A box is initially at rest on a horizontal, frictionless table. If a force of 10 Newtons acts on the box for 3 seconds, what is the momentum of the box at the end of the 3 second i
population inversion The process in which the number of electrons (N 2 ) in a higher energy state called ‘metastable state of an active medium is increased to a value greate
An ideal Rankine cycle uses water as a working fluid, which circulates at a rate of 80 kg/s. The boiler pressure is 6 Mpa, and the condenser pressure is 10 kpa. The water enters th
When the wavelength of wave remains unchanged, the scattering is known as elastic.
a. A certain radioactive material emits gamma rays with energy 1 MeV. Another sample of radioactive material emits gamma rays with energy 10 keV. If both of these emit the same amo
A house is air conditioned using solar energy. Solar radiation heats a pressurized tank such that the temperature is maintained at 175 o C. 1500 kJ must be extracted from the hous
What is the mass ms of one 294Uus atom, in SI units? Include the error bars in your answer, using 1 atomic mass unit 1u = (1.66053892 ± 0.00000007) × 10-27 kg.
