Determine the heat energy required to vaporize 13.9 grams of liquid water at 100° c. o 2,006 cal o 47.8 cal o 7,506 cal o 24.9 cal

Calculate the kinetic energy of earth due to its spinning about its axis. krot = j compare your answer with the kinetic energy of the orbital motion of earth's center of mass about the sun. assume earth to be a homogeneous sphere of mass 6.00 1024 kg and radius 6.40 106 m. the radius of earth's orbit is 1.50 1011 m.

The long handle on a rake is a(n) a. lever b. screw c. wedge d. inclined plane

The mass of the sun is 1.99×1030kg and its distance to the earth is 1.50×1011m. what is the gravitational force of the sun on the earth?
