The correlation between two observed variables is -0.84. from this, it can be concluded that the relationship between the two variables is strong but inverse (opposite direction).

<h3>What is correlation?</h3>

Correlation is one of the several measures of the linear statistical relationship between two random variables, indicating both the strength and direction of the relationship.

The correlation coefficient denoted by r is used to measure the strength and direction of a linear relationship between two random variables. of two variables.

The r value is between 0 and 1 and the closer to 1 indicates the strength of the relationship Also, when the r is negative, it is an indication that both variables move in the opposite direction.

Therefore, the correlation between two observed variables is -0.84. from this, it can be concluded that the relationship between the two variables is strong but inverse.

When we add or remove energy from a substance, what kind of changes can we observe? Can they happen at the same time ?
const2013 [10]

Answer:

When you add energy to a substance?

One change of state happens when you add energy to the substance. This change of state is called melting. By adding energy to the molecules in a solid the molecules begin to move quicker and can break away from the other molecules. The temperature at which a substance goes from a solid to a liquid is it melting point.

When you remove energy from a substance?

When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.

Explanation:

The addition of energy increases the kinetic energy of the particles, which reduces the intermolecular forces between the particles. Freezing occurs when a liquid becomes a solid and energy is released.

Atoms lose energy when they change from solid to liquid or gas and quid to gas.

EastWind [94]

When a beam of light  that is, at first, in air and oriented perpendicular to the surface of a body of water be deflected as a result of transition into water--------It does not deflect , the light direction will not change.

What happens to light when it passes through air?

All materials have what is known as an index of refraction, which is linked to how fast light can travel through the material. As light passes through air and into another clear material (such as glass), it changes speed, and light is both reflected and refracted by the glass.

How does light travel through air and water?

When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line.
