Answer:
Weathering
Explanation:
The geologic process of breaking down rocks into smaller and smaller units or pieces is known as weathering.
The physical disintegration and chemical decomposition of rocks to form sediments and soils is known as weathering.
The agents of weathering are wind, water and glacier.
- Chemical weathering entails the decomposition of rocks.
- Mechanical weathering is the physical disintegration of rocks.
Therefore, weathering breaks down rocks.
Erosion removes the weathered materials.
If the 30 N on the rope were pulled straight up, it would offset the force of gravity ( m g = 10 kg * 9.8 N/kg = 98 N) , leaving a net force up from the ground on the sled of 98-30 = 68 N. Since the rope is pulled at the angle of 25o, only part of the force is in the upward direction, (30N)(sin(25) = (30)(.423) = 12.7. So the net force becomes 98 N down offset by 12.7 up or 98-12.7 = 85.3 N. Ah, there it is: C.
