An F-4 aircraft makes a high-speed pass over an airfield on a day when;the temperature is 35°Q. The aircraft flies at M= 1.4 and 200-m altitude. Assume the constant air temperature up to-the altitude of 200 m. (a) Calculate the speed of the aircraft, and (b) how long after the aircraft passes directly overhead does its Mach cone pass a point on the ground?

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?

Which body part transports oxygen removes waste materials in carries nutrients to the body as part of the circulatory system

Suppose a soccer ball is kicked from the ground at an angle 20.0º above the horizontal at 8.00 m/s. the y-velocity is determined to be 2.74 m/s. how long will the ball be in the air? assume the ball lands at the same height at which it was kicked.
