Scientists studying bull sperm whales off the coast of South Africa have calculated that these mammals can descend to depths of nearly 3,000 m during their search for food. What is this depth in kilometers?

Describe uniform velocity and variable velocity in short

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
