Answer:
Horizontal force = 89.2 N
Explanation:
The frictional force = coefficient of friction * magnitude of the force (weight of the body) * cos theta
Substituting the given values, we get -
Frictional Force = 0.3*300 * cos 25 = 89.2 N
Horizontal force = 89.2 N
Most of our knowledge about Earth's interior comes from Seismic waves. Thus, option C is correct.
<h3>What is seismic waves</h3>
Seismic waves are created by abrupt movement of elements within the Earth, including fault rupture during an earthquake. Seismic waves can be caused by volcanic eruptions, blasts, landslides, rock slides, and even flowing rivers.
Seismic waves, also known as compressional or longitudinal waves, push and pull the earth in the direction of motion. Seismic waves provide the majority of our information about the Earth's innards. As a result, option C is correct.
