Show that y = YmaxCos(x -t) T is a solution to the wave equation 1 azy v² at² with the wave velocity being related to the wavelength and period by v = T

NO NEED TO SHOW ANY WORK JUST FINAL ANSWER AS QUICKLY AS POSSIBLE! A vacationer gets into his outboard motorboat and leaves a dock on a river bank for a day of fishing. Just as he turns upstream, he hears a splash but pays no attention and continues cruising at normal speed. Unfortunately, only 10 minutes later does he realize that his (fortunately watertight) lunchbox is missing. He then turns downstream, with the motor still set at cruising speed. Luckily, he sights his lunchbox floating down the river and retrieves it at a point 1  km downstream of the dock.

Suppose that the speed that a fish can swim depends on the 3/2 power of the length of the fish. Also suppose that that a herring with the length of 0.30 meters swims at a speed of 1.67 m/s.  a)Find the particular equation showing the relationship between swimming speed and length for this herring b)

Sine and cosine have period 2π.

What is the component of F along axis AB?

If you have a only a single pendulum and the string is 20 cm how much time would it take to swing it 10 times? And I hat would the period be?
