What is Slowly Leaking Box?
An ideal gas of atoms of number density at an absolute temperature is restricted to a thermally isolated container that has a small hole of area A in one of the walls. Assume a Maxwell velocity distribution for the atoms. The size of the hole is a lot smaller than the size of the container and much smaller than the mean free path of the atoms.
a) Evaluate the number of atoms arresting the wall of the container per unit area per unit time. (Express your answer in terms of the signify velocity of the atoms.)
b) What is the ratio of the average kinetic energy of atoms departure the container to the average kinetic energy of atoms primarily occupying the container? Presume that there is no flow back to the container. Give a qualitative argument and calculate this ratio.
c) How much heat necessity you transfer to/from the container to keep the temperature of the gas constant?
A plane monochromatic wave travelling in a homogeneous medium goes into a denser medium. What are the changes in (i) Frequency (ii) amplitude (iii) speed of propagation & (iv) Phas
Describe a) Potential difference between two points V, B) Intensity of electric field E. Derive the relation between them.
Stress is measured by the deforming force per unit normal area. Stresses set up in an object due to of the action of forces can be divided into three broad categories (a) Ten

UNIFORM VELOCITY: If a body covers equal displacements in equivalent intervals of time, though the smallest intervals may be, then the velocity of the body is said to be unifor
1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. II. The relationship between an object''s mass m,
Johannes Kepler revealed three empirical laws by using the data on planetary motion, pertaining to the orbit of planets. These laws are contained here because of the huge importanc
