Explanation

Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity.

Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.

Explanation

• In a parallel circuit, if one bulb blows, the other bulb will remain the same.
• This is because each bulb in a parallel circuit has its own independent path to the power source.
• The failure of one bulb does not affect the current flowing through the other bulb's path.

Explanation

The male gonads in rabbits, as in all mammals, are the testes (singular: testis).

The testes are responsible for producing sperm and testosterone.

Explanation

The moon's surface is covered with a layer of fine dust called regolith.

This layer consists of tiny fragments of rock and mineral particles created by meteorite impacts.

Explanation

Chloroplasts contain various pigments like chlorophyll, carotenoids, and phycobiliproteins, which absorb light of different wavelengths.

This allows plants to capture a broad spectrum of light energy and use it for photosynthesis.

Explanation

Ba is the chemical symbol for Barium, a chemical element with atomic number 56.

It is a soft, silvery-white alkaline earth metal.

Explanation

The presence of an enzyme does not affect the nature or properties of the end products of a chemical reaction.

Enzymes only speed up the reaction, they do not change the final result.

The end products are the same, regardless of whether an enzyme is present or not.

Explanation

The Boolean expression for an AND gate is A . B, where A and B are the inputs.

This expression reads "A and B".

In Boolean algebra, the AND operation is represented by a dot (.) or a logical multiplication symbol (∧).

So, the expression A . B or A ∧ B represents the AND operation.

Explanation

When a wire is placed perpendicular to a magnetic field, the force on the wire is proportional to the current flowing through it.

If the current increases, the force on the wire will also increase.

Explanation

A magnifying glass is also known as a simple microscope.

Because it magnifies objects, making them appear larger than they actually are.

It is called "simple" because it consists of a single lens.
