Explain how a rollercoaster converts potential energy to kinetic energy

Biology
1 answer:
Tomtit [17]3 years ago
7 0
When the coaster ascends one of the smaller hills that follows the initial lift hill, its kinetic energy changes back to potential energy. In this way, the course of the track is constantly converting energy from kinetic to potential and back again.

Now we need to prepare a buffer that has a pH of 7.4. We need this specific pH to
Anestetic [448]

Answer:

b) By mixing weak base with its conjugate acid and then adjusting the pH with strong  acid.

Explanation:

Hello,

In this case, considering that the buffer required a pH greater than 7 where the basic conditions are present, we need a weak base and its conjugate base in order to assure such pH greater than 7. Moreover, by using a strong acid, we can gently add it in order to decrease the pH up to 7.4 via a properly measured neutralization of the necessary moles of base up to a hydrogen concentration of 3.98x10⁻⁸ (pH). Therefore, answer is b) By mixing weak base with its conjugate acid and then adjusting the pH with strong  acid.

Best regards.

The atoms of elements sometimes become "sequestered" in the environment. which of the following is an example of this?
Marta_Voda [28]

d. carbon atoms in ocean water

Explanation:

The carbon atoms in ocean water is one of the ways through which carbon is sequestered in nature.

Sequestration of carbon implies the storage of carbon either naturally or artificially for a very long time.

Carbon sequestration cuts off carbon from the normal biogeochemical cycle and stores it in natural reservoirs for a very long duration.

  • In nature, carbon is sequestered a whole lot through biological and chemical activities.
  • Phytoplanktons are food producers. When consumed by higher organisms, their organic materials which contains carbon can become sequestered when the consumer dies and falls to the bottom of the ocean.
  • Organisms that used carbonate to manufacture their shells in the ocean also sequesters carbon.
