Answer:
The second answer from the top, no the energy in the wave pushed the water particles from above the earthquake in the opposite direction.
Explanation:
I believe this is the correct answer. Hope you do well
The correct answer is option C. <span>All objects reflect some light. If the object is in front of a mirror, the mirror reflects the light back toward the object, and an image is formed by the reflected rays.</span>The mirror reflects light and does not absorb. Reflection can be specular or diffused.
Answer:
400N
Explanation:
If you have 2 forces (200N) and (200N) pushing an object the same direction in a one dimensional force vectors, the answer would be 400N
Answer:
<em>The rubber band will be stretched 0.02 m.</em>
<em>The work done in stretching is 0.11 J.</em>
Explanation:
Force 1 = 44 N
extension of rubber band = 0.080 m
Force 2 = 11 N
extension = ?
According to Hooke's Law, force applied is proportional to the extension provided elastic limit is not extended.
F = ke
where k = constant of elasticity
e = extension of the material
F = force applied.
For the first case,
44 = 0.080K
K = 44/0.080 = 550 N/m
For the second situation involving the same rubber band
Force = 11 N
e = 550 N/m
11 = 550e
extension e = 11/550 = <em>0.02 m</em>
<em>The work done to stretch the rubber band this far is equal to the potential energy stored within the rubber due to the stretch</em>. This is in line with energy conservation.
potential energy stored =
==> = <em>0.11 J</em>
