Answer the following question given this paragraph: with a minus sign because the displacement while stopping and the force from floor are in opposite directions (cos = cos 180 = 1) . The floor removes energy from the system, so it does negative work. The kinetic energy the person has upon reaching the floor is the amount of potential energy lost by falling through height. Q: When someone falls, the kinetic energy the person has upon reaching the floor is the amount of what energy lost by falling through height? Choices: - gravitational energy - thermal energy - nuclear energy - potential energy A:
(A).
potential energy

Answer the following question given this paragraph: Mechanical weathering breaks rock into smaller pieces. These smaller pieces are just like the bigger rock; they're just smaller! The rock has broken without changing its composition. The smaller pieces have the same minerals in the same proportions. You could use the expression "a chip off the old block" to describe mechanical weathering! The main agents of mechanical weathering are water, ice, and wind. Q: What type of weathering breaks rock into smaller pieces? Choices: - fluid weathering - chemical erosion - chemical weathering - mechanical weathering A:
(A).
mechanical weathering
