Here are the answers to the given questions above.
1. The reason why a person might want to wear snowshoes if walking a distance in deep snow is that snowshoes spread the person’s weight out, snowshoes reduce the amount of pressure on a given spot, and snowshoes keep the person from sinking in the snow. So the answer is all of these.
2. The measure of the average kinetic energy of the particles of a substance is the TEMPERATURE.
3. Archimedes’ Principle helps to explain the relationship between buoyancy and density.
4. The one that is equal to the buoyant force of a rock placed in a beaker of water is weight of the displaced fluid.
Hope these answers help.
