Free Measurements MCQs with Answers

191. Physics is the quantitative science based primarily on:

• A. Definition
• B. Experiment and measurement
• C. Hypothesis
• D. A collection of skills

Explanation: Physics is primarily based on experiment and measurement. It relies on conducting experiments to observe natural phenomena, collecting empirical data through measurements, and using this information to formulate theories and laws that describe and predict the behavior of the physical world. While hypotheses and theoretical frameworks are crucial in physics, the discipline's foundation lies in experimentation and precise measurement to validate or refute these hypotheses.

192. The branch of science, which deals with the interaction of matter and energy, is called:

• A. Chemistry
• B. Mathematics
• C. Statistics
• D. Physics

Explanation: Physics explores the fundamental laws governing the universe, studying matter, energy, motion, and the forces acting upon them. It aims to explain natural phenomena through observations, mathematical models, and experimentation.

193. Some concepts of static electricity were introduced by:

• A. Greeks
• B. Chinese
• C. Thales
• D. Einstein

Explanation: Thales of Miletus, an ancient Greek philosopher, did indeed observe static electricity phenomena, such as the attraction of amber (a fossilized tree resin) to other objects after being rubbed. His observations of this phenomenon might be considered among the earliest documented references to static electricity.

194. The theory which modified the Newton's laws of motion for describing the bodies moving with speed comparable with the speed of light is:

• A. Electromagnetic Theory
• B. Faraday' laws
• C. Theory of relativity
• D. Collision theory

195. Astrophysics deals with:

• A. Particles in space
• B. Elementary particle
• C. Neutrons Protons
• D. Electrons

Explanation: Explanation of this question will be added soon!

196. The branch of sciences which deals with the properties of matter and energy along with the interaction between them is known as:

• A. Geography
• B. Geology
• C. Biology
• D. Physics

Explanation: The branch of science that deals with the properties of matter and energy, as well as their interactions, is called physics. Physics explores the fundamental principles governing the universe, encompassing various subfields like mechanics, thermodynamics, electromagnetism, quantum mechanics, and relativity.

197. Physics is the science based on:

• A. Interaction between matter and energy
• B. Energy of the material
• C. Mass of the material
• D. Neither energy nor matter

Explanation: Physics is primarily concerned with the interaction between matter and energy, including the properties of matter like mass, the various forms and transformations of energy, and the relationship between the two.

198. 65 mm is equivalent of approximately:

• A. 1.5 inches
• B. 2.6 inches
• C. 5.5 inches
• D. 10.5 inches

Explanation: To convert mm to inch, we divide the value provided in mm by 25.4. Hence,65 ÷ 25.4 = 2.6 inches.

199. Of the following the largest quantity is:

• A. 0.47 cm
• B. 47 x 10^-4 cm
• C. 4.7 x 10^-2 cm
• D. 0.0000047 x 10^4 cm

Explanation: Comparing all these values, the largest quantity is 0.47 cm, which corresponds to option A.

200. The mm is the unit of:

• A. Acceleration
• B. Distance
• C. Velocity
• D. Force

Explanation: The SI unit of distance is m where milli is the prefix.
