question 18

Multiple Choice

A horizontal disk rotates about a vertical axis through its center.Point P is midway between the center and the rim of the disk,and point Q is on the rim.If the disk turns with constant angular velocity,which of the following statements about it are true? (There may be more than one correct choice.)

• A) P and Q have the same linear acceleration.
• B) Q is moving twice as fast as P.
• C) The linear acceleration of Q is twice as great as the linear acceleration of P.
• D) The linear acceleration of P is twice as great as the linear acceleration of Q.
• E) The angular velocity of Q is twice as great as the angular velocity of P.

Definitions:

Optimal Solution

The best possible outcome or answer found through a process of optimization, considering all constraints and objectives.

Demand Constraints

Limitations or restrictions on the amount of goods or services that can be sold or provided, often due to market or resource capabilities.

Intuitive Method

A decision-making process based on natural instincts, feelings, or judgments rather than on formal analysis or logical reasoning.

Initial Feasible Solution

Initial Feasible Solution is the starting point in optimization and linear programming problems that meets all constraints and can be used as a basis for subsequent improvement.
