The solution to the problem is as follows:
Normal force is m*g plus 240 N*sin30.
<span>30 kg*9.8 m/s^2 + 240 N*sin30 = 414 N

Answer: physical or mechanical weathering
Explanation:
Mechanical weathering which is also referred to as the physical weathering occurs when a rock is broken down into smaller pieces. In this case, there will be a physical change of the rock but its composition will not change.
Some examples include ice freezing and expansion of the cracks in the rock, Smstrong winds that carrycpieces of sand which then sandblast surfaces, moving water which causes abrasion etc.
If there’s no friction acting on either object then they will both be falling at a speed of 9.8m/s which is the force of gravity!
I think you meant what is "Dark matter" if so the answer is Dark matter is a hypothetical form of matter that is thought to account for approximately 85% of the matter in the universe.
