Reducing friction with pencils
Place round pencils under a heavy box. Join a string to the box and find the force required to move it across a table. Search the force needed to move the box without the rollers. Summarize the data get and suggest explanations for the results.

Ferromagnetic substances: on the basis of domain theory A. 1. In a ferro magnetic substance, large no. of domains occur. 2. The direction of magnetisation with in a
It is based on the photovoltaic effect. One of the semiconductor regions is made so thin that the light incident on it reaches the p-n junction and gets absorbed. It changes solar
Forging: Forging is shaping of metal either by impact or steady compression among a hammer or ram and anvil. Related to hammering or pressing of metal, the main difference among
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
Photon Interactions a. Consider a Si detector of 1 mm thickness. 10 6 photons each with energy of 100 keV are incident on the detector. Find the number of coherent, Compton, an
Q. Explain how Newton's ring can be obtained in the laboratory. Why Newton's rings are circular in shape? How the Newton's rings are used to find refractive index of liquid?
Q Define: specific rotation? Precise rotation for a given wavelength of light at a given temperature is defined as the rotation produced by one-decimetre length of the liquid c
Inductors are the electronic components designed especially for introducing a required amount of inductance in the circuit. They are coils of wires, wound around some magnetic mate
Depending upon the penetration power, there are two parts of X-rays Hard X-rays More penetration power More frequency of the order of ≈ 1019 Hz Lesser wavelength range
