Milk is poured into a bowl at a constant rate of 17.0 cm3/s. The bowl has a circular cross section, but does not have a uniform diameter. (That is, different horizontal cross sections taken at different heights of the bowl have different diameters.) (a) As the milk fills the bowl, the milk level reaches a point where the diameter of the bowl is d1 = 1.45 cm. What is the rate (in cm/s) at which the milk level rises at this diameter? (b) As the milk continues to fill the bowl, the milk level reaches a point where the diameter of the bowl is d2 = 5.30 cm. What is the rate (in cm/s) at which the milk level rises at this diameter?

After Dan makes a basket, Josephine claims she can find the amount of time the ball was in the air (from the time it leave's Dan's hand to the time it enters the basket). 10 ft Josephine says she can do this by using Dan's equation ( h (t) = - 16t2 +18t + 8) and setting the equation equal to zero. Dan doesn't think Josephine's thinking is correct. Who do you agree with? Explain your reasoning using mathematical evidence. 0/10000 Word
Angular momentum (L) of a thin slice rotating around an axis is given by 1. L = mr"wm where w is angular velocity, defined as w = 2nf The SI unit of L is kg.m²/s. r is the radius, m is the mass and fis the frequency. Find the values of n and m by doing dimensional analysis.

On December 26, 2004, a great earthquake occurred off the coast of Sumatra and trig- gered immense waves (tsunami) that killed some 200, 000 people. Satellites observing these waves from space measured 800 km from one wave crest to the next and a period between waves of 1.0 hour. What was the speed of these waves in m/s and km/h? Does your answer help you understand why the waves caused such devastation?
