What we have here is the ultimate physics trivia quiz it offers a chance to ensure that you do not forget some of the basic principles and theories surrounding this study. Do you need a refresher or a way to charge up your day using physics? Well, this test will do exactly that. Give it a shot and see how well you will do.

• 1.

What do thermometers measure?

• A.

Average Kinetic energy.

• B.

The amount of particles in an object.

• C.

The specific heat.

• D.

None of the above.

A. Average Kinetic energy.
Explanation
Thermometers measure the average kinetic energy of particles in an object. Temperature is a measure of the average kinetic energy of the particles in a substance. When the temperature increases, the average kinetic energy of the particles also increases, causing them to move faster. Thermometers use this principle to measure and indicate the temperature of an object or environment. The other options, such as the amount of particles in an object or the specific heat, are not directly measured by thermometers.

• 2.

A wavelength is the..?

• A.

How many waves pass a certain point in a certain amount of time.

• B.

Distance between a crest and the next crest.

• C.

Distance between a trough and the next trough.

• D.

Both B and C.

D. Both B and C.
Explanation
The correct answer is Both B and C. A wavelength is the distance between a crest and the next crest or between a trough and the next trough. This is because a wave consists of alternating crests and troughs, and the wavelength measures the distance between these points. Therefore, both options B and C accurately describe what a wavelength is.

What is a mechanical wave?

• A.

A mechanical wave is a wave that requires a medium to travel through.

• B.

A mechanical wave is a wave that can travel through the vacuum of space

• C.

A mechanical wave is made from gears and steam power.

• D.

A mechanical wave is not something that exist.

A. A mechanical wave is a wave that requires a medium to travel through.
Explanation
A mechanical wave is a wave that requires a medium to travel through because it relies on the transfer of energy through the vibration or oscillation of particles in the medium. Unlike electromagnetic waves, such as light or radio waves, which can travel through a vacuum, mechanical waves need a physical substance, such as air, water, or solid material, to propagate. This is because the particles in the medium are disturbed by the wave's energy and transmit it to neighboring particles, causing a chain reaction that allows the wave to travel.

Who was the first to state the principle of flotation?

• A.

Issac Newton

• B.

Archimedes

• C.

Aristotle

• D.

Galileo

B. Archimedes
Explanation
Archimedes was the first to state the principle of flotation. This principle, also known as Archimedes' principle, states that an object will float in a fluid if the buoyant force acting on it is equal to or greater than the weight of the object. Archimedes discovered this principle while trying to determine if a crown made for King Hiero II was made of pure gold. He realized that the crown displaced its weight in water, leading him to understand the concept of buoyancy. His contribution to the understanding of flotation has had a significant impact on various fields, including engineering and naval architecture.

On which of these factors, Buoyancy depends?

• A.

Density of the fluid

• B.

Volume of the body

• C.

Both a & b

• D.

None of the above

A. Density of the fluid
Explanation
Buoyancy depends on the density of the fluid in which the body is submerged. When an object is placed in a fluid, it experiences an upward force called buoyant force. This force is equal to the weight of the fluid displaced by the object. The density of the fluid determines how much weight of the fluid is displaced, thus affecting the buoyant force. The volume of the body also plays a role in determining the buoyancy, as it affects the amount of fluid displaced. Therefore, both the density of the fluid and the volume of the body are factors on which buoyancy depends.
