Q. An electromagnetic wave has a wavelength of 6.00 X 10^-6 m. In what region of the electromagnetic spectrum is this radiation? why?

Q. A liquid with density of 1.65 x10 cubed kg/m cubed flows through 2 horizontal sections of tubing joined end to end. in the first section, the cross-sectional area is 10.0 cm2. the flow speed is 275 cm/s, and the pressure is 1.20 times 10 to the fifth pa. in the section, the cross sectional area is 2.50 cm squared.
