In solids, heat is move from conduction. We will study conduction of heat energy by a solid bar in the following section.
Given a solid bar of thickness and area of cross-section A. The left side of the bar is get at a temperature ΦA and right side at ΦB.
Let us consider that ΦA > ΦB.
Heat moves from high to low temperature i.e., from left side to right side, as given in fig.
After some time, temperature of each section becomes constant with time. This is called as steady state.
Classical Mechanics and Electromagnetism Classical Mechanics , which study with the motion of bodies under the action of forces. This is often known as Newtonian mechanics as
Can a solid and liquid together be possible? Actually, substances can exist in all three states of matter concurrently if the conditions are right. The triple point of a substa
A boy throws a ball of mass 20 kg vertically upwards.It raises to a maximum height of 100 m.At what height will the kinetic energy be reduced to 70%?
The energy needed to ionize an atom is known as ionization energy. It is the energy needed to make the electron jump from the present orbit to the infinite orbit.
3 scenarios: You have an object such as a jar, and you submerge it under water to 50m depth. (Every 10m down increases pressure by 1 bar, thus the pressure is 5 bar). Scenario 1:
A satellite is goes form the surface of earth vertically and then is turned horixontally in space as it requires to revolve around the earth.
A metal has a work function of 4.80 eV. Will ultraviolet radiation with a wave length of 385 nm be able to eject a photoelectron from the metal?
If 10 9 electrons move out of a given body to another body every second, how much time is required to get a total charge of 1C of the other body? ------------------------------
It is a parameter of an insulator that defInes the maximum voltage difference that can be applied across the material before the insulator collapse and conducts.
Organ pipes are the musical instruments which are used for making musical sound by blowing air into the line. Longitudinal stationary pulses are created on account of superimpositi
