Question 2
Open questionState Newton’s First Law of Motion with an example.
A: Motion changes without any force
B: Rest and motion continue until an external force acts ✓
C: Only valid for planets
D: Only applies in vacuum
Correct Answer: B — B: Rest and motion continue until an external force acts ✓
Law of Inertia: A body remains at rest or in uniform motion unless acted upon by an external force.
Question 3
Open questionWhich type of lens is used to correct myopia (short-sightedness)?
A: Convex lens
B: Concave lens
C: Cylindrical lens
D: Plano-convex lens
Correct Answer: B — B: Concave lens
Concave lenses are used to correct myopia because they diverge light rays before reaching the eye.
Question 4
Open questionWhich law of thermodynamics states that energy cannot be created or destroyed?
A: Zeroth law
B: First law
C: Second law
D: Third law
Correct Answer: B — B: First law
The First Law of Thermodynamics states that energy can neither be created nor destroyed, only transformed.
Question 5
Open questionSound cannot travel through which of the following?
A: Solid
B: Liquid
C: Gas
D: Vacuum
Correct Answer: D — D: Vacuum
Sound requires a medium (solid, liquid, or gas) to travel, so it cannot travel through a vacuum.
Question 6
Open questionAccording to Ohm’s law, V = ?
A: IR
B: I/R
C: R/I
D: I+R
Correct Answer: A — A: IR
Ohm’s law states that V = IR, where V is voltage, I is current, and R is resistance.
