Earthquakes can produce three types of waves. One of these is a
transverse wave called an S wave. A
typical S wave travels at 500m/s. Its
wavelength is about 420 meters.
What is its frequency?
A. 1.19 Hz. Perpendicular
B. 0.84 Hz, Perpendicular
C. 1.19 Hz, Parallel
D. 0.84 Hz, Parallel

Which two objects have the greatest gravitational force acting between them

Note: the following questions are unrelated to the balmer series or the martian. refer to your course notes. a sun-sized star will spend most of its lifetime as a: white dwarf b. red giant c. protostar d. main-sequence star

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
