Suppose that water waves coming into a dock have a velocity of 1.2 m/s and a wavelength of 2.4 m. With what frequency do these waves meet the dock?

Identify the type of synthetic material used in each object

Astone is dropped with no initial velocity from the top of a cliff and hits the ground a time of 3.9 s later. what is the height of the cliff, in units of meters? you may assume that air resistance is negligible. give the answer as a positive number question 15 a figure skater is rotating at a rate of 200 revolutions per minute. what is the angular speed, in units of rad/s? 200 o 20.9 12000 o 3.33
