A possible means for making an airplane invisible to radar is to coat the plane with an antireflective polymer. If radar waves have a wavelength of 2.50 centimeter and the index of refraction of the polymer is n = 1.70, explain how thick would you make the coating? (Suppose that the index of refraction of the plane is higher than that of the coating.)
The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.10 . At this new distance, the speed of the block is observed to be 3.50. Explain by how much work was done by the person who pulled on the cor..
How much work did the movers do (horizontally) pushing a 150- crate 10.2 across a rough floor without acceleration, if an effective coefficient of friction was 0.50.
A vertical scale on a spring balance reads from 0 to 160 N. The scale has a length of 12.5cm from the 0 to 160 N reading. A fish hanging from the bottom of spring oscillates vertically at the frequency of 2.30 Hz. ignoring the mass of the spring, wha..
