A tuning fork produces a wave at 280 Hz and with a wavelength of 1.5 m. Calculate its velocity.

The speed of light is 3 „e 108 m/s (300,000,000 m/s). Red light has a wavelength of 7 „e 10-7 m (0.0000007 m). What is its frequency?

During a rain storm, rain comes straight down with a velocity -15 m/s and hits the roof of a car perpendicularly. The mass of the rain per second that strikes the roof is .060 kg every second. Assuming that the rain cones to rest upon stiking the car (Vf...
