Quiz with answers and explanations
Question 1. What is the SI unit for measuring temperature?
a) Celsius
b) Fahrenheit
c) Kelvin
d) Rankine
Answer
c) Kelvin
Explanation
What is the SI unit for measuring temperature?
- Explanation: The Kelvin (K) is the base unit of temperature in the International System of Units (SI). It’s used in scientific contexts and is important because it starts at absolute zero, the theoretical lowest possible temperature.
Question 2. What does the term ‘ampere’ measure in physics?
a) Force
b) Electric current
c) Energy
d) Resistance
Answer
b) Electric current
Explanation
What does the term ‘ampere’ measure in physics?
- Explanation: The ampere (A) measures electric current. It’s a fundamental SI unit and represents the flow of electric charge per second. One ampere of current represents one coulomb of electrical charge moving past a specific point in one second.
Question 3. What is measured using a barometer?
a) Wind speed
b) Humidity
c) Atmospheric pressure
d) Temperature
Answer
c) Atmospheric pressure
Explanation
What is measured using a barometer?
- Explanation: A barometer is used to measure atmospheric pressure. Pressure is an indicator of weather changes; high pressure often correlates with good weather, while low pressure indicates stormy weather.
Question 4. In physics, what does the ‘candela’ measure?
a) Luminous intensity
b) Mass
c) Electric charge
d) Time
Answer
a) Luminous intensity
Explanation
In physics, what does the ‘candela’ measure?
- Explanation: The candela (cd) measures luminous intensity, or the power emitted by a light source in a particular direction. It is one of the seven base units in the SI and provides a measure of the intensity as perceived by the human eye
Question 5. What is Planck’s constant used to measure?
a) Magnetic field strength
b) Energy of photons
c) Acceleration
d) Voltage
Answer
b) Energy of photons
Explanation
What is Planck’s constant used to measure?
- Explanation: Planck’s constant is used to calculate the energy of photons (light particles). It’s a fundamental constant in quantum physics, symbolized by ‘h’, and relates the energy of a photon to its frequency: E = hf, where E is energy, h is Planck’s constant, and f is frequency.
Question 6. What is the unit of measure for frequency?
a) Hertz
b) Pascal
c) Joule
d) Watt
Answer
a) Hertz
Explanation
What is the unit of measure for frequency?
- Explanation: The unit of measure for frequency is the hertz (Hz). Frequency refers to the number of occurrences of a repeating event per unit time, and 1 Hz means one cycle (or occurrence) per second.
Question 7. In the context of physics, what does ‘lumen’ measure?
a) Temperature
b) Luminous flux
c) Power
d) Electric current
Answer
b) Luminous flux
Explanation
In the context of physics, what does ‘lumen’ measure?
- Explanation: The lumen (lm) measures luminous flux, the total quantity of visible light emitted by a source. Unlike the candela, which measures the intensity of light in a particular direction, lumens measure the total visible light output from a source.
Question 8. What device is commonly used to measure the velocity of an object?
a) Thermometer
b) Barometer
c) Radar gun
d) Hygrometer
Answer
c) Radar gun
Explanation
What device is commonly used to measure the velocity of an object?
- Explanation: A radar gun or a speedometer is commonly used to measure the velocity of an object. A radar gun uses the Doppler effect to measure speed, while a speedometer in a vehicle measures the speed of the vehicle itself.
Question 9. What is the unit of measurement for force?
a) Ampere
b) Newton
c) Watt
d) Coulomb
Answer
b) Newton
Explanation
What is the unit of measurement for force?
- Explanation: The unit of measurement for force is the newton (N). Force is a physical quantity that represents the push or pull on an object. One newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared.
Question 10. What physical property is measured in pascals?
a) Temperature
b) Energy
c) Pressure
d) Frequency
Answer
c) Pressure
Explanation
What physical property is measured in pascals?
- Explanation: The pascal (Pa) is the SI unit for measuring pressure. Pressure is the force exerted per unit area, and one pascal equals one newton per square meter. It’s used in various applications, from weather forecasting to engineering.
