A weight is connected to a spring that is suspended vertically from the ceiling. If the weight is displaced downward from its equilibrium position and released, it will oscillate up and down.If air resistance is neglected, will the total mechanical energy of the system (weight plus Earth plus spring) be conserved?

A. Yes
B. No

Answers

Answer:

Yes

Explanation:

Neglecting air resistance, the total mechanical energy of the system would be conserved because the two forces acting on the weight are the spring force and the gravitational force, and both are conservative in nature.

Which explains earthquakes and volcanic eruptions?global positioning theory
lithospheric theory
plate tectonics theory
nebular theory

Answers

Plate tectonics theory explains earthquakes and volcanic eruptions. Global positioning theory, lithospheric theory and nebular theory do not explain the earthquakes and volcanic eruptions

Answer:

C. Plate tectonics theory

Explanation:

According to the plate tectonics theory outer layer of earth is divided into seven major and some minor plates. And these plates form convergent,divergent and transverse boundaries. So the Pacific ring of fire, subduction zone, continental drift are evidences of plate tectonics theory. Earthquakes and volcanic eruption are also explained by plate tectonics theory.
