Originally, light is unpolarized. It then travels through 3 polarizers: the first with its transmission axis aligned vertical, the next at a 30 degree angle to the vertical and the last aligned at a 45 degree angle to the vertical (tilted the same direction as the first with respect to the vertical). The original intensity of light is 4 W/m2.Q. What is the intensity of light after the second polarizer?________W/m2Q. What is the intensity of light after the third polarizer?________W/m2Q. If the second polarizer is aligned at a 45 degree angle to the vertical (just like the third), what is the final intensity of light after the third polarizer?________W/m2
Explain how fast would it be moving after it had fallen a distance of 0.010 m? (Assume that the gravitational force is constant over the distance of the fall, and that the star is not rotating.)
A boy of mass 60.0 kg is rescued from a hotel fire by leaping into a firefighters' net. The window from which he leapt was 8.0 m above the net. What is the average force on the net due to the boy during the interval
Create a graph of x-position, x-velocity, and x-acceleration versus time and a graph of y-position, y-velocity, and y-acceleration versus time.
