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.
Why bulky group present at axial position of chair or boat conformer is less stable compared to equitorial position? Ans) Let the bulky group has a large mass M. suppose it is a
Q. A transistor is connected in CE configuration. The voltage drop across the load resistance ( Rc) 3 k is 6 V. Find the base current. The current gain α of the transistor is 0.97.
A Surfer sits on his board waiting as waves go by to catch a ride back to shore. Assuming the waves can be modelled as a sine wave given by h (x,t) = 1.75 sin (0.03 Πx - 0.15 Πt) [
Regard as a capacitor which is charged to 12 volts and then connected across a resistor. Allow t1/2 be the time it takes for the voltage to drop down to 6 volts. Presume the experi
