A girl is fishing at the end of a pier. She notices that her bobber moves up and down 5 times in 4.5 s. She also notices a 3.0 m long boat pointing perpendicular to shore. She counts 4 full waves along the length of the boat. A) What is the frequency of the waves? B) What is their period? C) What is the wavelength of the waves? D) What is their wave speed? E) If the pier is 41.0 m long, how long does it take the wave to travel from the end of the pier to the shore?

One end of a 1,20 m long string is attached to a tuning fork
with the frequency of 200Hz. On the other end of the string, hangs
a weight with the mass of 2kg over a pulley and stretches the
string. If the tuning fork is struck, a standing wave with 4 curves
is formed. (Standing wave is when one end of the wave is
fixed.)

URGENT A 400.0-m-wide river flows from west to east at 30.0 m/min. Your boat moves at 110 m/min relative to the water no matter which direction you point it. To cross this river, you start from a dock at point A on the south bank. There is a boat landing directly opposite at point B on the north bank, and also one at point C, 75.0 m downstream from B a)Where on the north shore will you land if you...
