Explanation

A force is a Push or a Pull that causes movement.

Explanation

The properties used to describe heat are:

• Hot (high temperature)
• Energy (thermal energy)
• Cold (low temperature)

Explanation

When the half of the Earth is facing away from the Sun, it experiences Night, as it is not receiving direct sunlight.

Explanation

• The pupil is the opening in the center of the iris that regulates the amount of light entering the eye, similar to the aperture in a camera.
• The iris controls the size of the pupil, adjusting the amount of light that reaches the retina.

Explanation

• A unit is a standard quantity that is used to measure other quantities of the same kind.
• For example, the meter is a unit of length, the kilogram is a unit of mass, and the second is a unit of time.

Explanation

• When we ascend or descend too quickly, our body struggles to adapt to the change in pressure, leading to altitude sickness or other injuries.
• This is why it's important to acclimate to higher elevations gradually, allowing our body to adjust to the decreasing pressure.

Explanation

• Pascal's Law states that the pressure applied to a fluid (liquid or gas) in a container is transmitted equally throughout the fluid and to the walls of the container, and that the pressure is the same in all directions at a given point in the fluid.
• This principle has numerous applications in engineering, physics, and everyday life.

Explanation

• Bacteria are used in genetic engineering because they have the ability to multiply quickly, allowing for rapid production of large quantities of recombinant DNA.
• This is especially true for E. coli, which has a short generation time and can produce large amounts of protein.

Explanation

• Force is a vector quantity.
• It means it has both magnitude (amount of force) and direction (the way it is applied).

Explanation

Kinetic energy is the energy an object has because of its motion.

If we want to accelerate an object, then we must apply a force.
