Thanks. I have it now. The class I am taking is an online class and they don't give very good examples to work on before the tests which are very hard problems.

mass = density * volume ?

So the FORCE = m*g*cos (theta) right?

Well, FORCE = Mass * gravity , right?

pressure is the force exerted on a surface divided by the area of the surface to which it is applied

It exerts its weight and it is the bottom side

response a downward force due to mass and gravity?

I have a question and I think it has too many unknowns, but here it is: Two spheres, labeled A and B, have identical masses, but are made of different substances. The specific heat capacity of sphere A is 440 J/kg*C . The spheres are initially at 21 degrees C; and the same quantity of heat is...

Have a dilemma on this problem: An ice cube, density = 917 kg/m^3, is sliding down a frictionless incline of 16 degrees. The sides of the cube each have a length of 0.75 m. What pressure does the cube exert on the incline? Any help out there?
