  1. What is the momentum of a 2 kg ball moving at 5 m/s?

    Answer: 10 kg·m/s

    Momentum equals mass times velocity: 2 kg × 5 m/s = 10 kg·m/s.

  2. Which electromagnetic wave has the longest wavelength?

    Answer: Radio waves

    Radio waves have the longest wavelength in the electromagnetic spectrum.

  3. What is formed when an atom loses or gains electrons?

    Answer: An ion

    An atom that loses or gains electrons becomes a charged particle called an ion.

  4. According to Newton's third law, for every action there is an equal and opposite what?

    Answer: Reaction

    Newton's third law states every action force has an equal and opposite reaction force.

  5. What is the boiling point of pure water at standard atmospheric pressure?

    Answer: 100°C

    Pure water boils at 100°C at standard atmospheric pressure.

  6. Which quantity is a vector?

    Answer: Velocity

    Velocity has both magnitude and direction, making it a vector.

  7. A power rating of 60 watts means energy is used at a rate of:

    Answer: 60 joules per second

    One watt equals one joule per second, so 60 W means 60 joules per second.
