1. What type of energy does a stretched rubber band possess?

• A. Kinetic energy
• B. Potential energy
• C. Thermal energy
• D. Mechanical energy

Correct answer:

Rationale: When a rubber band is stretched, it stores potential energy due to its position or state.

2. Which preposition best completes the sentence: "She borrowed money _____ her friend."

• A. of
• B. from

3. What is the tough, fibrous tissue that connects bones at joints called?

• A. Cartilage
• B. Ligaments
• C. Tendons
• D. Fascia

Correct answer: B

Rationale: The correct answer is B: Ligaments. Ligaments are the tough, fibrous tissue that connects bones at joints. They provide stability and support to the joints, preventing excessive movement that could result in injury. Cartilage is a smooth, rubbery tissue that covers the ends of bones and cushions joints. Tendons are fibrous cords that attach muscles to bones, allowing for movement. Fascia is a connective tissue that surrounds muscles, groups of muscles, blood vessels, and nerves, providing support and protection. Therefore, in this case, the term that specifically refers to the tissue connecting bones at joints is ligaments.

4. What is the relationship between the frequency and period of a wave?

• A. They are unrelated
• B. Frequency = Period
• C. Frequency = 1/Period
• D. Period = 1/Frequency

Correct answer: D

Rationale: The correct relationship between frequency and period of a wave is that Period = 1/Frequency. This means that the period of a wave is the reciprocal of its frequency. Frequency is the number of complete cycles of a wave that occur in a unit of time, while the period is the time it takes for one complete cycle of the wave to occur. Since frequency and period are inversely related, the correct formula is Period = 1/Frequency.

5. A concave mirror can be used to:

• A. Focus light to a single point
• B. Only create virtual images
• C. Always magnify objects
• D. Scatter light

Correct answer: A

Rationale: A concave mirror can be used to focus light to a single point because of its reflective surface that curves inward. When light rays parallel to the mirror's principal axis strike the mirror, they converge at a focal point, creating a real image. This property makes concave mirrors useful in applications like reflecting telescopes and headlights, where focusing light to a point is necessary for proper functioning. Virtual images are also created by concave mirrors, but the primary function is to focus light rather than create virtual images. Magnification of objects and scattering of light are not inherent properties of concave mirrors.

• A. I have been working on this project since morning.

• C. They will be leaving for vacation tomorrow.
