Your professor has put 5 objects near the top of an inclined plane: a uniform density solid sphere, a hollow sphere, a hollow cylinder, a special solid cylinder in which the density is proportional to the radius (rho(r) = αr), and a solid cube. The spheres and cylinders have radius R and will roll down the plane, while the cube has sides of length 2R and a frictionless coating, so it will slide down the plane. All objects are released at the same time. Which is the last to get to the bottom of the plane?

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

mark brainliest i am trying to get to the next level!

i will be your freind and say    

gravitational energy

electrical energy

kinetic energy

ligh energy

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
