Two men and women are entrusted with a task. The second man needs three hours more to cope up with the job than the second man and the woman would need working together. The first man, working alone, would need as much time as second man and the woman working together. The first man working alone, would spend eight hours less than the double period of the time second man would spend working alone. How much time would the two men and the women need to complete the task if they all asked together?
Answer: Option 1 Difference in times required by the first man (A) and second man (B) = 3 hours. Also, if ta and tb are the respective times, then tb -...

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...
