1) A rectangular box (like the one shown in the theory) has a base with 6 cm sides, is 5 cm tall and has mass 120 grams. a) Calculate the volume of the box. b) Calculate the density of the box. c) Calculate the estimated depth to which the box will float in water. d) Calculate the buoyancy force on the floating box. e) Calculate how much additional mass could be added to the box before it begins to sink. f) Suppose the mass was added in the form of pennies. At most, how many pennies could be placed into the box without it sinking? (See section 2.3)

6) A liquid is flowing through a 57.0 cm ^ 2 The pipe is then reduced to 16.5 cm ^ 2 speed of the liquid is measured to be 6.05 m/s . What was the speed of the liquid in the larger pipe?

What would be the behavior of an object that was immersed in a fluid if the object and the fluid had the same density? Explain.
