F = ma The force of friction for a 7.5-kg object being pushed horizontally at a constant A 30-kg wooden box is resting on a carpeted surface. If the ... An applied force of 21 N accelerates a 9.0-kg wagon at 2.0 m/s² along the sidewalk. (u=0,034. 5. A sled of mass of 50.0 kg is pulled along a flat, snow-covered ground.
Explanation:
Answer:
R = V^2 sin 2 θ / g range formula
R is a maximum for θ = 45 and R = V^2 g
g = V^2 / R = 3^2 / 15 = .6 m/s^2
Answer:
sediments
Explanation:
Weathering is the breakdown of rocks into smaller particles called:
sediments
Weathering is the physical disintegration and chemical decay of rocks into smaller fragments to produce sediments. The product of rock weathering is basically sediments. Some of the sediments can be transformed to form soils when they combine with organic matter, water and air.
Physical weathering is when rocks are physically broken into smaller pieces, but the minerals in the rock remain the same.
Physical weathering
Physical weathering is the disintegration of rocks into smaller bits without altering the chemical make up of the minerals. The goal of physical weathering is to expose rock surface to action of chemical weathering.
When a rock is broken down in a way that changes the mineral composition, it is called chemical weathering
chemical weathering
Chemical weathering is the decay of rocks by altering the minerals in a rock.
