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