Answer:
When it is in position one because it gathers all the energy to fall and slowly gets faster.
Answer:
false
Explanation:
Mars has no rings. the only planets that do are Jupiter, Saturn, Neptune, and Uranus
Answer/Explanation: On Mercury temperatures can get as hot as 430 degrees Celsius during the day and as cold as -180 degrees Celsius at night.
Mercury is the planet in our solar system that sits closest to the sun. The distance between Mercury and the sun ranges from 46 million kilometers to 69.8 million kilometers. The earth sits at a comfy 150 million kilometers. This is one reason why it gets so hot on Mercury during the day.
The other reason is that Mercury has a very thin and unstable atmosphere. At a size about a third of the earth and with a mass (what we on earth see as ‘weight’) that is 0.05 times as much as the earth, Mercury just doesn’t have the gravity to keep gases trapped around it, creating an atmosphere. Due to the high temperature, solar winds, and the low gravity (about a third of earth’s gravity), gases keep escaping the planet, quite literally just blowing away.
Atmospheres can trap heat, that’s why it can still be nice and warm at night here on earth.
Mercury’s atmosphere is too thin, unstable and close to the sun to make any notable difference in the temperature.
Space is cold. Space is very cold. So cold in fact, that it can almost reach absolute zero, the point where molecules stop moving (and they always move). In space, the coldest temperature you can get is 2.7 Kelvin, about -270 degrees Celsius.
Sunlight reflected from other planets and moons, gases that move through space, the very thin atmosphere and the surface of Mercury itself are the main reasons that temperatures on Mercury don’t get lower than about -180 °C at night.
General transcription factors are involved in the formation of a preinitiation complex. The most common are abbreviated as TFIIA, TFIIB, TFIID, TFIIE, TFIIF, and TFIIH
The categories of energy expenditure include the following:
- Resting metabolic rate - This is the total number of calories burned when your body is completely at rest and accounts for 60-75 percent
- Thermic effect of feeding - This happens during feeding in which the metabolic rate increases and heat is produced and accounts for 5-15 percent
- The thermic effect of activity - the amount of energy burned during all physical activity and accounts for 15-30 percent.
<h3>What is Energy expenditure?</h3>
These are the processes which involves how energy is used or spent. The categories are mentioned above with their appropriate explanations.
