- For each polariser the angle given is the one for which light is transmitted and is given clockwise from the vertical. Horizontally polarised light is shone on a polarise that is angled at 35^circ to the vertical. If th e incoming light has amplitude 200Vm^-1 and intensity 53Wm^-2 work out: Part A Amplitude a) the amplitude of the transmitted light;
- Base your answer to the following question on the diagram below and on your knowledge of E science. The diagram represents the Moon's orbit around Earth. Explain why the Moon's period of revolution and period of rotation cause the same side of the to always face Earth.
- Activity: 1. At t=0s. a particle moving in the x-y plane with constant acceleration has a velocity ofoverrightarrow (v)_(i)=(3hat (i)-2hat (j))m/s, and is at the origin. Att=3s, the particle's velocity is overrightarrow (v)_(f)=(9hat (i)+7hat (j))m/s. Find (a)the acceleration of the particle (b) Its coordinates at t=3s
- Ultrasound was used to check for cracks in an aeroplane wing. The ultrasound pulse would be reflected from any cracks and from the end of the wing. The diagram shows the oscilloscope trace produced by the echo . How long was the plane wing? The speed of sound in metal is 5000m/s (Time is measured in miliseconds Remember that I second equals 1000 miliseconds.]
