To find the reactance XLXLX_L of an inductor, imagine that a current I(t)=I0sin(ωt)I(t)=I0sin⁡(ωt), is flowing through the inductor. What is the voltage V(t)V(t)V(t) across this inductor? Express your answer in terms of I0I0I_0, ωωomega, and the inductance LLL.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
