Which of the following statements is true?The wave has a speed of 0.2 m/s and propagates in the positive x-directionThe wave has a frequency of 3 Hz and propagates in the positive x-directionThe wave has a frequency of 3 Hz and propagates in the negative x-directionThe wave has a speed of 5 m/s and propagates in the positive x-directionThe wave has a wavelength of 2 m and propagates in the negative x-direction

An aircraft performs a maneuver called an "aileron roll." during this maneuver, the plane turns like a screw as it maintains a straight flight path, which sets the wings in circular motion. if it takes it 35 s to complete the circle and the wingspan of the plane is 11 m, what is the acceleration of the wing tip

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?
