The circumference of a circle is given by $2\pi r$, so the answer is approximately $44$ cm.

Physics

What happens to the speed of sound when it travels through a denser medium?
The speed of sound increases as it moves through a denser medium because particles are more closely packed, allowing faster transmission of vibrations.

Why does a moving object eventually stop if no external force is applied?
Due to friction, which opposes motion and converts kinetic energy into heat, causing the object to slow down and stop.

What is Newton’s third law of motion?
For every action, there is an equal and opposite reaction.

Why does an object appear to be weightless in space?
In space, objects experience free fall due to the absence of significant gravitational resistance, making them appear weightless.

What happens to the kinetic energy of an object if its speed is doubled?
Kinetic energy is proportional to the square of speed, so if speed doubles, kinetic energy increases by four times.

A magnifying glass is a convex lens that bends light to focus it, making objects appear larger.

Why do astronauts wear special suits in space?
Space suits provide oxygen, protect from radiation, and maintain body pressure in the vacuum of space.

What is the principle of conservation of energy?
Energy can neither be created nor destroyed; it can only change from one form to another.

Chemistry

Why does salt dissolve in water?
Salt dissolves in water because water molecules surround and separate the salt ions, breaking them apart.

Why is diamond harder than graphite, even though both are made of carbon?
Diamond has a strong three-dimensional network of carbon bonds, whereas graphite has layers that can slide over each other.

What is rusting, and how can it be prevented?
Rusting is the reaction of iron with oxygen and water to form iron oxide. It can be prevented by painting, galvanizing, or using stainless steel.

Why do ice cubes float in water?
Ice is less dense than water because its molecules form a structured lattice, making it occupy more space.

Metals have free-moving electrons that allow electrical current to pass through them.

Why does lemon taste sour?
Lemons contain citric acid, which stimulates sour taste receptors.

Why does a candle flame go out when covered with a glass?
The flame goes out because the oxygen supply is cut off, preventing combustion.

Why does soap remove grease better than water alone?
Soap molecules break down grease by surrounding and lifting oil particles, making them easier to wash away.

The iron reacts with copper sulfate, forming iron sulfate and depositing copper on the nail.

Biology

Why do we need oxygen to survive?
Oxygen is required for cellular respiration, a process that releases energy from food.

Why do leaves appear green?
Leaves contain chlorophyll, which absorbs all colors of light except green, which is reflected.

How do vaccines work?
Vaccines introduce a harmless form of a virus or bacteria, prompting the immune system to develop defenses against it.

Why do we get muscle cramps after exercise?
Cramps occur due to the buildup of lactic acid in muscles when oxygen supply is low.
