What is an example of a reservoir?
1. Beach
2. Cloud
3. Desert
4. Lake

Answers

Answer 1

I think that the best answer is Lake.

A reservoir (/ˈrɛzərvwɑːr/; from French réservoir [ʁezɛʁvwaʁ]; lit. 'storehouse') is, most commonly, an enlarged natural or artificial lake, pond, or impoundment created using a dam or lock to store water.

Please give brainiest if correct, would rlly appreciate it :D

Answer 2

Answer:

Lake

Explanation:

The meaning of reservoir is a large natural or artificial lake used as a source of water supply.

PROCESS OF ELIMINATION

 ____________________

A beach is not a reservoir.

Clouds have little water so we cannot do that.

Desserts have little to no water

That just leaves us with 4, (Lake)

what energy transformation occur when propane gas is used to lift a hot air balloon?

A. Mechanical --> light --> chemical
B. Chemical ---> mechanical --> light
C. thermal --> chemical --> light
D. chemical --> thermal --> mechanical

Answers

Answer:

the answer is D. chemical, thermal, and mecanical

The energy transformation occur when propane gas is used to lift a hot air balloon is Chemical-> mechanical-> Light.

What is Propane gas role in hot air balloon?

Propane can be produced from the components of liquid which is recovered during natural gas processing. Also these components include ethane, methane, propane, and butane, as well as heavier hydrocarbons.

The molar mass of propane is C₃H₈ - (12x3) + (1x8)= 44 g/mol.The number of moles of propane present - 0.200 mol1 mol weighs - 44 gMass of propane present  - 8.8 g

The energy conversion for the propane, that is, energy transformations that occur when propane gas is used to lift the balloon will be:

The chemical propane will be burned at first.All the process in the balloon will be checked and concluded as good mechanism without any leakage.When the propane gas was fired the balloon goes up and its gets lifted with thermal energy.The thermal energy give the Light.

Thus, the process can be simplified as the Chemical energy converting to mechanical energy which later converted to thermal energy and to the Light energy.

Hence, Option B is the correct answer.

In this image of Earth and the Moon from the Sim, what does the circle around Earth represent?

Answers

Answer: This is the orbit (of the moon around Earth).

An orbit is a circular/oval path that planets, moons, comets, etc follow with a "subject" in the middle. In this case, the circle is the orbit of the moon around Earth.

The circle around the earth represents the orbit.

What is an orbit?

It is considered to be the regular, repeating path where one object should be in space that takes around the another one. The object in the orbit known as the satellite. It could be in natural way such as earth or moon. Also, it is the circular oval path where the planets, moons could follow the subject.

Therefore, The circle around the earth represents the orbit.

According to Archimedes' principle, when an object is placed in a fluid, the buoyant force acting on it is equal to the weight of the fluid the object displaces. Question 3 options: True False

Answers

But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is the weight of the object. Thus, only in the special case of floating does the buoyant force acting on an object equal the object's weight

What is the thermal energy of an object?

Question 2 options:

Its average temperature


Its ability to conduct heat.


The amount of radiation it emits.


The total kinetic and potential energy of its particles


please include explanation

Answers

The thermal energy of an object is the energy contained in the motion and vibration of its molecules. Thermal energy is measured through temperature. The energy contained in the small motions of the object's molecules can be broken up into a combination of microscopic kinetic energy and potential energy.

Answer:The total kinetic and potential energy of its particles

Explanation:

A transverse wave has oscillations (movements) where the particles move perpendicular to the direction the wave is traveling. This means:

A. Both the medium and the energy move forward together

B. As the energy in the wave moves forward the medium moves up and down

C. As the medium moves forward the energy moves up and down

The gravity of Earth is attracting a person towards the center with 500N of gravitational force. The person is exerting a reactionary force on the Earth with how much force? Explain your thinking behind this.

Answers

Answer:

500n

Explanation:

Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
