Two sources emit beams of light of wavelength 550 nm. the light from source a has an intensity of 10 µw/m2, and the light from source b has an intensity of 20 µw/m2. this is all we know about the two beams. which of the following statements about these beams are correct? (there could be more than one correct choice.)a) a photon in beam b has twice the energy of a photon in beam a. b) a photon in beam b has the same energy as a photon in beam a. c) beam b carries twice as many photons per second as beam a. d) the frequency of the light in beam b is twice as great as the frequency of the light in beam a. e) none of the above statements are true.

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
