- 20 mm
- 200 mm
- 1000 mm
- 2000 mm
Show answer and explanation
Answer: D. 2000 mm
1 cm = 10 mm, so 200 cm × 10 = 2000 mm.
Practise 398 real Federal Board Physics questions from 2023 to 2026. See an answer and explanation as soon as you answer.
Matric Physics is examined by the Federal Board of Intermediate and Secondary Education (FBISE) in the annual examinations, for 9th and 10th class. Tayyari Karo has real questions from 2023 to 2026, covering topics such as Current Electricity, Dynamics, Physical Quantities and Measurement, Kinematics and Properties of Matter. Working through real papers is the fastest way to learn the paper pattern and the way questions are worded.
120 of the questions are multiple choice and marked instantly; the rest are short and long questions with a model answer. The answers are prepared by Tayyari Karo, since we could not find an official marking scheme.
These are real past-paper questions. Think of your answer first, then open the explanation.
How many millimetres are there in 200 cm?
Answer: D. 2000 mm
1 cm = 10 mm, so 200 cm × 10 = 2000 mm.
A car moving at 40 ms⁻¹ slows down to 20 ms⁻¹ in 4 s. Its retardation is:
Answer: C. −5 ms⁻²
a = (vf − vi)/t = (20 − 40)/4 = −5 ms⁻². The negative sign shows retardation.
When a body is taken from the Earth to the Moon, then:
Answer: C. its mass remains the same but its weight decreases
Mass is the quantity of matter and does not change. Weight = mg, and g on the Moon is about 1/6 of that on Earth, so weight decreases.
What is inertia? Give one example.
Inertia is the property of a body due to which it resists any change in its state of rest or of uniform motion. It depends on the mass of the body — greater mass means greater inertia.
Example: When a moving bus stops suddenly, passengers fall forward because their bodies tend to keep moving (inertia of motion). Similarly, a coin on a card placed over a glass falls into the glass when the card is flicked away (inertia of rest).
