Answer and give correct reason. I will rate accordingly.

SUBJECT: PHYSICS

a. What is meant by buoyancy and how much is it if a solid object is in liquid fluid.  b. A liquid fluid is in the glass and the glass moves straight at a constant speed, what force acts on the liquid fluid?  c. If the glass rotates at a constant angular velocity, what would the surface shape of the liquid fluid be? d.  If the glass moves with a constant acceleration, what will the shape of the surface of the liquid object be?

What is the state of water if the pressure is 10 MPa and the specific volume is 0.003 m 3 /kg?       a. Ice  b. Liquid c. Liquid and vapor mixture d. Vapor

9. Niagara Falls is about 50 m high. a. What is the temperature rise in kelvins of the water from just before it goes over the cliff to just after it hits the rocks at the bottom of the falls, assuming negligible air resistance during the fall and that the water doesn't rebound but just splats onto a rock? It is helpful (but not essential) to consider a 1 g drop of water. b. In the Niagara Falls hydroelectric generating plant, the energy of falling water is converted into electricity. Assuming that the energy conversion is highly efficient, approximately how much energy is obtained from one kilogram of falling water? Approximately how many kilograms of water must go through the generators every second to produce a megawatt of power (1 x 106 W)?
