-
Q1.The phenomenon responsible for the blue colour of the sky is:
Show answer & explanation
Answer: D — Rayleigh scattering
Shorter (blue) wavelengths are scattered more by air molecules.
-
Q2.A body with initial velocity 15 m/s accelerates at 2 m/s² for 5 s. Find the distance covered.
Show answer & explanation
Answer: B — 100 m
s = ut + ½at² = 15×5 + ½×2×5² = 100 m.
-
Q3.Acceleration due to gravity on Earth’s surface is about:
Show answer & explanation
Answer: B — 9.8 m/s²
g ≈ 9.8 m/s².
-
Q4.Find the power dissipated when 1.5 A flows through a 12 Ω resistor.
Show answer & explanation
Answer: C — 27 W
P = I²R = 1.5² × 12 = 27 W.
-
Q5.Absolute zero is:
Show answer & explanation
Answer: D — −273.15 °C
0 K = −273.15 °C.
-
Q6.Find the power dissipated when 1 A flows through a 2 Ω resistor.
Show answer & explanation
Answer: D — 2 W
P = I²R = 1² × 2 = 2 W.
-
Q7.The SI unit of power is the:
Show answer & explanation
Answer: D — Watt
1 watt = 1 joule per second.
-
Q8.A body starts at 7 m/s and accelerates uniformly at 6 m/s² for 8 s. Find its final velocity.
Show answer & explanation
Answer: B — 55 m/s
v = u + at = 7 + 6×8 = 55 m/s.
-
Q9.The upthrust on a body immersed in a fluid equals the weight of fluid displaced. This is:
Show answer & explanation
Answer: B — Archimedes’ principle
Archimedes’ principle.
-
Q10.A current of 0.5 A flows through a 4 Ω resistor. What is the potential difference across it?
Show answer & explanation
Answer: D — 2 V
Ohm’s law: V = IR = 0.5 × 4 = 2 V.
How to approach physics questions
Write the formula before substituting and keep SI units throughout. Most numerical questions use one of: v = u + at, s = ut + ½at², F = ma, KE = ½mv², V = IR, P = I²R.
