Answer:
A. It uses less energy to make something from recycled materials than from new materials.
Explanation:
I think it is this one because it is the only one that is not harmful to the environment. Also, I took the test a few minutes ago.
To get it to start moving, he have to exert a force equal to its maximum force of static friction.
F= fs,max = Ms m g= (0.21) * (180) * (9.8) = 370 N
Let me know if im wrong but if not brainliest user for helping or best answer
The answer is B. They can only go through solid NOT liquid
C) Y is the strongest point in the electric field.
The time taken for the mass to reach the bottom of the inclined plane after it is released from rest is 0.78 s.
<h3>
Height of the inclined plane</h3>
The height of the inclined plane is calculated as follows;
h = L(sin 37)
where;
- h is height of the plane
- L is length of the plane
h = 5 x sin(37)
h = 3.01 m
<h3>Time of motion of the mass</h3>
t = √(2h/g)
t = √(2 x 3.01 / 9.8)
t = 0.78 s
Thus, the time taken for the mass to reach the bottom of the inclined plane after it is released from rest is 0.78 s.
