A Particle Is in Simple Harmonic Motion Along the X

question 2

Multiple Choice

A particle is in simple harmonic motion along the x axis. The amplitude of the motion is x_m. At one point in its motion its kinetic energy is K = 5J and its potential energy (measured with U = 0 at x = 0) is U = 3J. When it is at x = x_m, the kinetic and potential energies are:

• A) K = 5J and U = 3J
• B) K = 5J and U = -3J
• C) K = 8J and U = 0
• D) K = 0 and U = 8J
• E) K = 0 and U = -8J

Definitions:

Economies of Scale

Refers to the cost advantages that enterprises obtain due to their scale of operation, with cost per unit of output generally decreasing with increasing scale.

Economies of Scale

Cost advantages reaped by companies when production becomes efficient, leading to a decrease in the per-unit cost as output increases.

Diseconomies of Scale

The situation in which the cost of producing each individual unit rises when a company's production volume grows, often resulting from inefficiencies and a rise in complexity.
