Q1. The unit of work is:

(A) Joule
(B) Neutron
(C) Watt
(D) Dyne

Show Answer ▼

Correct answer is Joule. Work is measured in joules in SI units. It represents the energy transferred when a force acts over a distance.

Q2. The unit of power is:

(A) Hertz
(B) Volts
(C) Watt
(D) Neutrons

Show Answer ▼

Correct answer is Watt. Power is the rate of doing work. In SI units, it is measured in watts.

Q3. In SONAR, we use:

(A) Radio waves
(B) Audible sound waves
(C) Ultrasonic waves
(D) Infrasonic waves

Show Answer ▼

Correct answer is Ultrasonic waves. SONAR uses high-frequency sound waves to detect underwater objects. Radio or audible waves are not used.

Q4. The liquid used in a simple barometer is:

(A) Water
(B) Mercury
(C) Alcohol
(D) All of these

Show Answer ▼

Correct answer is Mercury. Its high density allows accurate measurement of atmospheric pressure. Water or alcohol are not commonly used.

Q5. Richter scale is used for measuring:

(A) Velocity of sound
(B) Intensity of light
(C) Amplitude of seismic waves
(D) Intensity of sound

Show Answer ▼

Correct answer is Amplitude of seismic waves. Richter scale measures the strength of earthquakes using seismic wave amplitude.

These Physics MCQ Questions are useful for not only nursing exams but also for all competitive exams where General Science knowledge is tested. By practicing regularly, you can master concepts of motion, energy, forces, heat, light, sound, and electricity. Each MCQ is carefully designed to simulate real exam conditions and comes with explanations, ensuring you learn the why behind every answer.

Q6. The intensity of an earthquake is measured in:

(A) Richter scale
(B) Decibel scale
(C) pH scale
(D) Celsius scale

Show Answer ▼

Correct answer is Richter scale. It measures the strength of earthquakes using seismic wave amplitudes.

Q7. Which one is not correctly matched?

(A) Celsius – Temperature
(B) Kilowatt hour – Electricity
(C) Rh factor – Blood
(D) Richter scale – Humidity

Show Answer ▼

Correct answer is Richter scale – Humidity. Richter scale measures earthquake magnitude, not humidity.

Q8. Which of the following is a seismometer device?

(A) Crescograph
(B) Seismograph
(C) Geiger Counter
(D) Raingauge

Show Answer ▼

Correct answer is Seismograph. It is a device that records earthquake vibrations. Other devices are for measuring growth, radiation, or rainfall.

Q9. Which device is used to measure the intensity of an earthquake?

(A) Seismograph
(B) Stethoscope
(C) Cosmograph
(D) Periscope

Show Answer ▼

Correct answer is Seismograph. It measures earthquake intensity by recording vibrations. Other devices are unrelated.

Q10. What does a ‘seismograph’ record?

(A) Heart-beats
(B) Atmospheric pressure
(C) Earthquake
(D) None of the above

Show Answer ▼

Correct answer is Earthquake. A seismograph records vibrations caused by earthquakes.
