Q. the knowledge of reynolds number(r) tells, whether the flowof
a liquid through a pipe will be streamlined or not. by themethod of
dimensions, find the expression for reynold number, if itdepends
upon the velocity (v) of the flow of the liquiddensity()
of the liquid, coefficient of viscosity()of
the liquid and diameter(d) of the pipe.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
