A boat crosses a river of width 121 m in which the current has a uniform speed of 0.654 m/s. The pilot maintains a bearing (i. e., the direction in which the boat points) perpendicular to the river and a throttle setting to give a constant speed of 2.52 m/s relative to the water. What is the magnitude of the speed of the boat relative to a stationary shore observer

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.

The law of reflection states that the angle of reflection is equal to the angle of
