  1. A hydraulic press has a small piston with area 5 cm² and a large piston with area 50 cm². If 10 N is applied to the small piston, what force is exerted by the large piston?

    Answer: 100 N

    Pascal's principle: force ratio equals area ratio; 10 × (50/5) = 100 N.

  2. Which of these materials is the BEST conductor of electricity?

    Answer: Copper

    Copper is a metal with free electrons, making it an excellent electrical conductor.

  3. A wheel with radius 0.5 m rolls forward one full revolution. How far does it travel?

    Answer: π m

    Distance per revolution = circumference = 2π × radius = 2π × 0.5 = π meters.

  4. A 3D object has 6 faces, 12 edges, and 8 vertices. What shape is it?

    Answer: Cube

    A cube has exactly 6 faces, 12 edges, and 8 vertices, satisfying Euler's formula (V − E + F = 2).

  5. Two springs are connected in series. Spring A has a spring constant of 100 N/m and Spring B has a spring constant of 100 N/m. What is the combined spring constant?

    Answer: 50 N/m

    Springs in series: 1/k_total = 1/100 + 1/100 = 2/100; k_total = 50 N/m.

  6. A container holds 2 liters of water. If it is tilted at 45°, assuming it does not spill, the water surface will:

    Answer: Remain horizontal

    Water always finds its own level due to gravity — the surface remains horizontal regardless of container tilt.
