Answer:
Observation 1 represents a solar wind because solar winds are a continuous stream of particles given off by the sun.
Explanation:
Answer:
1380 kph west
Explanation:
The resultant velocity is the sum of airplane velocity with respect to air and the velocity of wind with respect to ground. Since these 2 vectors are in opposite direction (east vs west), we will take the 20 kph east as negative
1400 west + 20 east = 1400 west + (-20)west = 1380 kph west.
Total amount of energy would remain constant according to law of conservation of energy. i.e., 50 Joules
In short, Your Answer would be Option C) <span>50 Joules because as energy converts from one form to another, it cannot be created or destroyed during the conversion.

<h3><u>Answer;</u></h3>
- Almost all of the energy on Earth comes from the Sun.
- The energy in fossil fuels originally came from the Sun.
- Plants convert the energy of sunlight into chemical energy.
<h3><u>Explanation</u>;</h3>
- <u>Many different forms of energy are used here on surface of the earth, but almost all of them originate from the sun, not just light and heat (thermal) energy.</u>
- <u>Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis.</u> Animals eat plants and use that same chemical energy for all their activities
- Heat energy from the sun causes changing weather patterns that produce wind. Wind turbines then convert wind power into electrical energy.All these conversions to different forms obeys the law of conservation of energy.
- <em><u>Fossil fuels are energy sources that were created over very long periods of time from decayed and fossilized living matter, and energy in these living organisms originally came from the sun.</u></em>
While gravitational pull pulls us down the opposing force pusshes us upward and cancels each other out
