Describe the two main ways that energy travels through the Sun.
ValentinkaMS [17]

Answer:

The energy are traveled through the sun in two ways that are:

  • By the radiation
  • By the convection

As, the energy are first traveled outward from the core of the sun and then it get entered in the zone of the radiation and this zone is known as radiative zone in the surface of the sun.In the radiation process some amount of the hydrogen particle are combined and then releases the energy. And the convection is the process of conversion of one form of energy to another form.

If I were to fill a water bottle full of air and go up in elevation, would the water bottle expand or shrink? If I were to fill
alina1380 [7]

Answer:

a. It would shrink

b. It would expand

Explanation:

a. Since the water bottle is filled with air at atmospheric pressure at 20000 ft, and since atmospheric pressure decreases with altitude, when we go up in elevation.

The pressure exerted by the molecules of air in the water bottle seek to balance out the atmospheric pressure as we go higher. Since the atmospheric pressure exerted by the molecules of air in the atmosphere are greater than that exerted by the molecules of air in the water bottle, this causes the volume of the water bottle to decrease and thus shrinks the water bottle until the pressure balances out

b. Since the water bottle is filled with air at atmospheric pressure at 20000 ft, and since atmospheric pressure increases with decreasing altitude, when we go down in elevation.

The pressure exerted by the molecules of air in the water bottle seek to balance out the atmospheric pressure as we go lower. The water bottle expands until the atmospheric pressure outside equals the pressure inside the water bottle.this causes the volume of the water bottle to increase and thus expands the water bottle until the pressure balances out

A device that uses electromagnetic induction to transfer electrical energy from one circuit to another is a(n)_____.
Nutka1998 [239]

A device that uses electromagnetic induction to transfer electrical energy from one circuit to another is a transformer.

<h3>Which device uses electromagnetic induction to transfer electrical energy from one circuit to another?</h3>

  • A transformer is an electrical device that transfers energy from one electric circuit to another using the electromagnetic induction principle.
  • It is intended to change the AC voltage between the circuits while keeping the current's frequency constant.
  • A transformer work on the principle of electromagnetic induction in which flux is linked from primary to secondary.
  • Transformers accomplish this without establishing a conductive link between the two circuits. This is made feasible by using Faraday's Law of Induction, which explains how an electric circuit will interact with a magnetic field to produce an electromotive force (EMF).
