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.
a car has a mass of 34.01 kg. The race lasts 30 seconds. you think if the car attains an acceleration of .55 m/s^2 to attain a final velocity of 16.54m/s it will win the race. what
Explain logarithmic decrement? Evaluate the ratio of nth amplitude with 1st amplitude in case of under damped oscillation.
EXPLANATION: Whenever an interaction occurs among two objects, each object exerts the similar force on the other, but in the opposite direction and for the similar length of ti
Ionisation: If the amount of external energy is large enough the valence electron can gain sufficient kinetic energy (energy of movement) to be removed completely from its atom
A Rayleigh interferometer (as shown in the figure below) can be used to measure the index of refraction of air. Two transparent tubes (T 1 and T 2 ) are placed behind two slits. O
