The branch of science which deals with matter is called physic.

The correct answer is as follows:-

Convection is a form of heat transfer that is predominantly common in fluids, especially liquid and gas.

It occurs by the movement of a part of a substance from one place to another based on density and temperature differences. According to the law of thermodynamic, the heat transfer from the high temperature of the system to the low temperature the system.

A typical convection cell is made up of a liquid that is heated. The liquid part close to the heat source becomes warmer and rises due to its low density.

The part away from the heat source is denser and begins to sink. This analogy is commonly demonstrated in a boiling pot of water.

Hence, the correct answer is mentioned above.

True

Explanation:

Convection is a form of heat transfer that is predominantly common in fluids especially liquid and gas.

It occurs by the movement of a part of substance from one place to another based on density and temperature differences.

A typical convection cell is made up of a liquid that is heated. The liquid part close to the heat source becomes warmer and rises due to its low density. The part away from the heat source is more dense and begins to sink.

This analogy is commonly demonstrated in a boiling pot of water.

Answer from: Quest

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange

Which statements describe the motion of car a and car b? check all that apply.

Answer from: Quest

the unit of the measure = $\frac{j}{kgk}$

explanation:

the property that is quantified by the energy needed per of material to raise the temperature by one.

si unit of energy = joule (j)

si unit of temperature = kelvin (k)

si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is $\frac{j}{kgk}$

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
