Petroleum Products
Petroleum and its products are mainly composed of carbon polymers (chains), as the backbone, with different structural and functional groups. Plastic, for example, is made of polypropylene and polybutylene which is mainly made of carbon atoms, whose monomers are linked in a chain to form polymers that make up the products.
Synthetic rubber on the other hand is made of copolymers of carbon and other addictives such as styrene. Synthetic fiber is made of nylon that is composed of a copolymer between carboxylic acid and amides.
Answer:
The answer is 306 m/s^2
Explanation:
F = m*a
We can rearrange this formula to get a = F / m.
The SI unit for mass is kilograms (kg).
The SI unit for acceleration is m/s^2.
There are 1000 grams in a kilogram.
7.20 g = 0.00720 kg
Force (2.20 N) / 0.00720 kg = 305.56 m/s^2
Accounting for Sig Figs, the answer is 306 m/s^2.
Gee, that's one fast bullet.
Sustain Life and Growth
Air consists one of the main life-sustaining gas called oxygen. Almost all living things breathe in and breathe out this air. Nitrogen and Carbon dioxide are also other gases that are vital for plants and their growth.
Combustion
Apart from this, air supports burning or combustion. The oxygen present in air help in burning of the fuels to basically carry out activities like cooking food, running industries and vehicles as well as generating heat and electricity.
Temperature Control
Another important aspect of air is that it helps in maintaining the temperature on the earth surface by circulating hot and cold air. Air acts as a conductor of heat as well. Even phenomena such as water cycle are dependent on air.
Supplier of Energy
Air which consists of energy is one of the main suppliers of energy. Living things are made up of cells and these cells extract oxygen within the blood to produce energy usually in the form of ATP. This biochemical generation of ATP is essential to maintain life on the earth.
Photosynthesis
Carbon dioxide, which is a component of air is used by plants during the process of photosynthesis. Here oxygen is also released by plants. And we already know how vital oxygen is.
Answer:
diversity throughout all living organisms
Answer:
The true statement is: "Spring tides are the highest, while neap tides are the lowest."
Explanation:
- The range of difference in the level of water between high and low tide is always larger in spring tide.
- Neap tides are the moderate tides. It does not have huge difference in higher and low tides because the bulging of the ocean ( by the sun) balances the bulge of the ocean caused by the moon.
- This balance is not found in spring tides that is the main reason for spring tides to have the highest level for both higher and lower tides.
