Wet Penguins Wet Penguins A rectangular block of ice 14 m on each side and 0.8 m thick floats in sea water. The density of the sea water is 1025 kg/m3. The density of ice is 917 kg/m 1) How high does the top of the ice block float above the water level?
2) How many penguins of mass 15 kg each can stand on the ice block before they get their feet wet?

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

(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.)
