Explanation

• Wind produces kinetic energy, which is the energy of motion.
• This kinetic energy is used to rotate the blades of a fan or turbine in a wind energy system.
• It converting the wind's kinetic energy into mechanical energy, and ultimately into electrical energy.

Explanation

• Cone cells are responsible for vision in bright light and color vision.
• There are three types of cone cells, each sensitive to different parts of the visual spectrum, which allows us to see a range of colors.

Explanation

Explanation

• An Addition Reaction is a type of chemical reaction where two or more substances combine to form a new, single compound.
• This type of reaction involves the formation of a new chemical bond, resulting in a single product with a unique identity.

Explanation

The statement "Total mass of the reactants and products will remain conserved during a chemical reaction" is called the Law of Conservation of Mass.

Explanation

• Satellites in orbit around the Earth use sensors and cameras to collect data and images of the planet's surface, atmosphere, and oceans.
• It enabling remote sensing applications such as land use mapping, crop monitoring, and natural disaster management.

Explanation

• A spacecraft is a man-made object designed to perform specific tasks in space.
• Such as exploration, communication, or research. 
• Examples of spacecraft include satellites, space stations, and probes.

Explanation

• A barometer measures atmospheric pressure by measuring the height of a mercury column that is supported by the pressure of the surrounding air.
• The higher the mercury column, the higher the atmospheric pressure.

Explanation

• Litmus paper is a simple and effective way to test whether a substance is an acid or a base.
• It turns red in acidic solutions and blue in basic solutions.

Explanation

• A chemical reaction is a process in which one or more substances are converted into new substances, often with a change in chemical composition and properties.
• Chemical reactions involve the breaking and forming of chemical bonds, resulting in a transformation of the original substances.
