The answers are:
1. Compaction - grains move closer together.
2. Foliation - parallel alignment of platy grains.
3. Recrystallization - grains take on a larger size.
4. Burial metamorphism - when a rock changes because of surrounding pressure.
Compaction produce rocks that have a tighter grain arrangement due to heat and pressure the rock undergoes. This process reduces the size of the rock.
Foliation occurs when pressure is put on one side of the grains more than any other direction. This creates platy structured rocks, which align under pressure.
Recrystallization is a process where the chemical composition a rock is changed. The mineral grains that are produced in this process are larger than the original grains.
Burial metamorphism occurs when rocks get buried deeper and deeper. They change due to the pressure from the overlying layers.
Answer:
1 m/s
Explanation:
Momentum before the collision = momentum after the collision
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
(3000 kg) (2 m/s) + (3000 kg) (0 m/s) = (3000 kg) v + (3000 kg) v
6000 kgm/s = 6000 kg v
v = 1 m/s
<span>a) The law of conservation of momentum is satisfied because there must be air (and other combustion byproducts) expelled behind the aircraft as it moves forward. The collective momentum of those gases is equal in magnitude and opposite in direction to the forward momentum of the aircraft.
b) The aircraft obeys conservation of energy because it is simply converting energy to different forms. In its stationary form, there existed latent chemical energy in both the fuel on board and the oxygen in the air. As the aircraft moves, some of that chemical energy is converted into kinetic energy and heat, but it is indeed conserved.</span>
Current = (charge) / (time) = (2.5) / (0.0002) = <em>12,500 Amperes</em>
The only thing wrong with the answer "12500" is that it lacks a unit.
Answer:
Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

this is what i know but i am sorry if this doesn't help
