Q1.Absolute zero is:
Show answer & explanation
Answer: B — −273.15 °C
0 K = −273.15 °C.
-
Q2.What force is needed to accelerate a 26 kg mass at 7 m/s²?
Show answer & explanation
Answer: A — 182 N
F = ma = 26 × 7 = 182 N.
-
Q3.Which mirror is used as a rear-view mirror in vehicles?
Show answer & explanation
Answer: D — Convex
Convex mirrors give an erect, diminished image and a wide field of view.
-
Q4.Find the kinetic energy of a 3 kg body moving at 20 m/s.
Show answer & explanation
Answer: B — 600 J
KE = ½mv² = ½ × 3 × 20² = 600 J.
-
Q5.The speed of light in vacuum is approximately:
Show answer & explanation
Answer: C — 3 × 10⁸ m/s
c ≈ 2.998 × 10⁸ m/s.
-
Q6.Find the power dissipated when 2.5 A flows through a 25 Ω resistor.
Show answer & explanation
Answer: C — 156.25 W
P = I²R = 2.5² × 25 = 156.25 W.
-
Q7.The bending of light as it passes from one medium to another is:
Show answer & explanation
Answer: D — Refraction
Refraction is caused by a change in light’s speed.
-
Q8.What force is needed to accelerate a 4 kg mass at 7 m/s²?
Show answer & explanation
Answer: A — 28 N
F = ma = 4 × 7 = 28 N.
-
Q9.Which colour of visible light has the longest wavelength?
Show answer & explanation
Answer: B — Red
Red light has the longest wavelength (~700 nm).
-
Q10.A body with initial velocity 6 m/s accelerates at 5 m/s² for 5 s. Find the distance covered.
Show answer & explanation
Answer: A — 92.5 m
s = ut + ½at² = 6×5 + ½×5×5² = 92.5 m.
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.
