1. Eight kilometers below the surface of the ocean the pressure is 82Mpa. Determine the density of the seawater at this depth if the density at the surface is 1025kg/m3 and the average bulk modulus of elasticity is 2.3GPa.
1kg block is placed at an inclined sloped at 10 degrees with the horizontal and is pushed up by a 150N force for 3 seconds from which then the 150N force is then removed. The block will continue sliding upward due to is momentum until it will completely stop. How far has the block traveled? if the coefficient of friction is 0.3 between the block and the inclined plane.
