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.
Five people are playing tug-of-war. Anders and Alyson pull to the right with 45 N and 35 N, respectively. Calid and Marisol pull to the left with 53 N and 38 N, respectively.
The higher power level band is called as the conduction band. (i) It is also called as empty band of minimum energy. (ii) This band is partially filled by the electrons. (
Which has additional rotational kinetic energy an object with a rotational inertia of 4 kg·m 2 and an angular velocity of 8 rad/s or else an object with a rotational inertia of 8
why is friction a necessary evil?
Two stable isotopes of lithium and have respective abundances of 7.5% and 92.5%. These isotopes have masses 6.01512 u and 7.01600 u, respectively. Find the atomic mass of lithium.
two insulated charged copper spheres A and B of identical size have charge q and -3q respectably .when they are brought in contact with each other and then separated,what are the n
As we''re on an inclined plane shouldn''t we take the x & y components of gravity into consideration?? thanks
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
theory to write the process of finding of neutral point of a bar magnet
Draw the final image formed by two lenses: An optical imaging system consists of two positive lenses (L1 and L2). L1 has a focal length f 1 = 10 cm, and L2 has a focal length
