Which of these is NOT a vector quantity: displacement, distance, electric field intensity or weight?
Answer: B. distance has magnitude only, so it is a scalar.
A car accelerates uniformly from 10 m/s to 40 m/s in 5 s. Find its acceleration.
Answer: B. a = (v − u) ÷ t = (40 − 10) ÷ 5 = 6 m/s².
A machine uses 1,400 J of energy and does 700 J of useful work. Find its efficiency.
Answer: A. Efficiency = output ÷ input × 100 = 700 ÷ 1,400 × 100 = 50%.
A spring of force constant 130 N/m is stretched by 5 cm. Find the force applied.
Answer: A. F = ke = 130 × 0.05 = 6.5 N (convert cm to m first).
A force of 50 N acts 60 cm from the pivot of a balanced lever. What force acting 100 cm on the other side balances it?
Answer: D. Principle of moments: 50 × 60 = F × 100, so F = 30 N.
A coin at the bottom of a tank of liquid 27 cm deep appears to be 18 cm below the surface. Find the refractive index of the liquid.
Answer: A. n = real depth ÷ apparent depth = 27 ÷ 18 = 1.5.
Which instrument measures relative humidity?
Answer: A. A hygrometer measures relative humidity.
One common use of microwaves is
Answer: A. Cooking food and satellite communication uses microwaves.
The becquerel is the SI unit of
Answer: B. The SI unit of activity of a radioactive source is the becquerel.
The acceleration due to gravity near the Earth's surface is about
Answer: B. g is approximately 9.8 m/s² (often rounded to 10 m/s²).
