A) A plastic block that has a length of 0.5 m, a width of 0.26 m, and a height of 0.33 m, and has a density of 670 kg/m3 floats in both water and oil. If the plastic block is floating at the surface of a tank of water (which has a density of 1000 kg/m3), what is the distance from the top of the block to the surface of the water?If the plastic block is floating at the surface of a tank of oil (which has a density of 900 kg/m3), what is the distance from the top of the block to the surface of the oil?

B) A cargo barge is loaded in a saltwater harbor for a trip up a freshwater river. If the rectangular barge is 2.50 m by 20.0 m and sits 0.800 m deep in the saltwater harbor, how deep will it sit in the freshwater river?

A large boat with 91.44 m in length and 42.672 m in width is carrying 1,360,777.11 kg of coal along the river with a 2.7432m draft (the height from waterline to bottom of the boat). What is the draft and weight of the boat when the boat is empty (no coal)? What is the draft and weight of the boat if the boat hits a wave and looses 10 tons of coal? Treat the boat as a rectangular cylinder. Use...

A spring has an unstretched length of 0.31 m. A block with mass 0.23 kg is hung at rest from the spring, and the spring becomes 0.37 m long. Next the spring is stretched to a length of 0.43 m and the block is released from rest. Air resistance is negligible. How long does it take for the block to return to where it was released? Next the block is again positioned at rest, hanging from the spring (0.37 m...

Find the length and width of the parabolic cylinder.

Let's suppose that you want to cook 1 lb of hot dogs using a parabolic trough concentrator on a clear June day in Los Angeles. The hot dogs would be skewered on a stiff piece of wire and aligned along the axis of the trough in the same position in which the absorber/receiver normally would be placed. The desired cooking time is 10 mins, with the resulting surface temperature of the hot dog about 450 F.Find the length and width...
