Starting from the results of Examples 5.4 and 5.5, estimate the number of cubic meters of water that would flow each second through an OTEC plant large enough ( 1000 M W e 1000 MWe) to provide electricity for Miami. Use the approximation of an ideal heat engine as in the examples. If this water flows at a velocity of 4 m / s 4 m/s, what would be the necessary diameter of the pipes?

While goofing off at the ice skating rink, a student takes off her shoes and places each of them on the ice. her friend, a hockey player, then shoots a hockey puck at each shoe. the first puck immediately comes to rest after it collides with the left shoe. the second puck rebounds after it collides with the right shoe. if each hockey puck has the same incoming speed, which shoe has greater speed after the collision? the right shoe. both shoes have the same speed. the left shoe.

What are the applications of electromagnetic waves

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
