Singapore GCE A-Level H1 Physics Practice Questions - Singapore GCE A-Level H1 Physics Examination (SEAB Syllabus 8867) Exam - Singapore GCE A-Level H1 Physics Practice Questions - Singapore GCE A-Level H1 Physics Examination (SEAB Syllabus 8867) Exam

Question 1

Which of the following represents the SI base units of electrical resistance (the ohm, Ω)?

kg m^2 s^-3 A^-2 kg m s^-2 A^-1 kg m^2 s^-2 A^-1 kg m^3 s^-3 A^-1

Correct Answer:

kg m^2 s^-3 A^-2

Question 2

Which statement correctly distinguishes between systematic errors and random errors in a physics experiment?

Systematic errors shift all readings in one direction and affect accuracy, whereas random errors cause scatter about a mean and affect precision. Systematic errors can be reduced by taking the average of multiple repeated readings, whereas random errors cannot. Systematic errors affect the precision of measurements, while random errors affect the accuracy. Systematic errors arise from unpredictable environmental fluctuations, whereas random errors arise from miscalibrated instruments.

Correct Answer:

Systematic errors shift all readings in one direction and affect accuracy, whereas random errors cause scatter about a mean and affect precision.

Question 3

Which pair of physical quantities consists of one scalar quantity and one vector quantity?

Work and Linear Momentum Impulse and Acceleration Power and Electric Potential Electric Field Strength and Force

Correct Answer:

Work and Linear Momentum

Question 4

A rectangular block has mass m = 200 ± 2 g and volume V = 50.0 ± 1.0 cm^3. What is the percentage uncertainty in the calculated density of the block?

3.0% 1.0% 2.0% 5.0%

Correct Answer:

3.0%

Question 5

The kinetic energy of an object is given by E_k = 0.5 m v^2. If mass m is measured with a percentage uncertainty of 2.5% and speed v with a percentage uncertainty of 2.0%, what is the percentage uncertainty in E_k?

6.5% 4.5% 9.0% 2.5%

Correct Answer:

6.5%
