Fourier's law of heat conduction is (where Q = Amount of heat flow through the body in unit time, A = Surface area of heat flow, taken at right angles to the direction of heat flow, dT = Temperature difference on the two faces of the body, dx = Thickness of the body, through which the heat flows, taken along the direction of heat flow, and k = Thermal conductivity of the body)?
Answer: Option 1 Fourier's law of heat conduction is k. A. (dT/dx) where Q = Amount of heat flow through the body in unit time, A = Surface area of heat...

Directions : Each of the following question consists of a statement followed by two arguments I and II. You have to decide which of the arguments is a STRONG arguments and which is a WEAK Argument. Statement : Should all refugees, who make unauthorized entry into a country, be forced to go back to their homeland Arguments : I. Yes. They make their colonies and occupy a lot of land. II. No. They leave their homes because of hunger or some terror and on human grounds, should not be forced to go back.?
Answer: Option 2 Clearly, refugees are people forced out of their homeland by some misery and need shelter desperately. So, argument II holds. Argument I against the statement is vague.
