  1. Which of the following electromagnetic waves has the highest frequency?

    Answer: Gamma rays

    Gamma rays have the highest frequency (and shortest wavelength) in the electromagnetic spectrum, carrying the most energy per photon.

  2. What is the chemical formula for glucose?

    Answer: C₆H₁₂O₆

    Glucose is a monosaccharide with the molecular formula C₆H₁₂O₆, containing 6 carbon, 12 hydrogen, and 6 oxygen atoms.

  3. Which of Newton's laws explains why a rocket accelerates as it expels exhaust gases?

    Answer: Third Law (Action-Reaction)

    Newton's Third Law states that for every action there is an equal and opposite reaction; the rocket expels gas backward (action) and is propelled forward (reaction).

  4. What is the process by which plants convert sunlight into chemical energy?

    Answer: Photosynthesis

    Photosynthesis is the process by which plants use sunlight, water, and CO₂ to produce glucose and oxygen, converting light energy into chemical energy.

  5. Which subatomic particle determines the atomic number of an element?

    Answer: Proton

    The atomic number of an element equals the number of protons in its nucleus; elements are defined and ordered on the periodic table by their proton count.

  6. A wave has a frequency of 50 Hz and a wavelength of 4 m. What is its speed?

    Answer: 200 m/s

    Wave speed = frequency × wavelength = 50 Hz × 4 m = 200 m/s.

  7. Which type of rock is formed from the cooling and solidification of magma or lava?

    Answer: Igneous

    Igneous rocks form from the cooling and solidification of molten magma (underground) or lava (at the surface), such as granite and basalt.
