A5 kg bowling ball, a 0.25 kg baseball, and a 0.05 kg golf ball are dropped from a 100-meter high building. a camera catches the motion of the balls as they pass specific markers (in meters, m) on the building. the times (in seconds, s) that each object passes the markers are listed in the table below. which of the following conclusions is true?
distance markers
object 10 m 25 m 50 m 100 m
bowling ball 1.41 s 2.24 s 3.16 s 4.47 s
baseball 1.41 s 2.24 s 3.16 s 4.47 s
golf ball 1.41 s 2.24 s 3.16 s 4. 47 s

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
