List two ways that a fuel cell differs from an ordinary battery

1 answer:

6 0

The simple answer is that in a battery the chemical reactions that produce the electrical current are produced from materials that are already in the battery itself, whereas in a fuel cell, the reactants, almost always Hydrogen and Oxygen are fed to the cell like an external fuel.

. However, while a battery makes electricity from the energy it has stored inside the battery, a fuel cell makes its electricity from fuel in an external fuel tank This means that while a battery may run dead, a fuel cell will make electricity as long as fuel is supplied. For hydrogen fuel cells, hydrogen is the fuel and it's stored in a tank connected to the fuel cell. When hydrogen in the tank runs low, you refill it, or replace it with a full tank.

<em>The correct option is B) 5-10%</em>

Explanation:

We have seen and depicted various scenarios where we see how different changes arise and dominate the world. Social scientists suggest that as low as 5-10% people of a population are enough to bring about a change because people tend to copy what others are doing. Same goes for countries of the world. Each new popular technique which is learnt by one country tends to become popular and learnt by other countries. For example, the usage of a social app starts with a few members of a population using it and with time it becomes popular in the whole world.

This question is incomplete because the images a section 2 are not given. I searched for the complete question but could not find it. However, based on my knowledge and the characteristics of the tundra this is the answer.

The correct answer is C. The climate is harsh, which limits the number of species that can live there.

Explanation

The tundra is the name of an ecosystem that occupies a fifth of the earth's surface, mainly in the northern hemisphere, this is characterized by having a frozen subsoil that limits the emergence and growth of natural vegetation and trees. This ecosystem is the coldest on the planet due to its location near the poles, its landscape is characterized by a layer of snow that covers most of the ground. In addition, the climatic conditions are extreme, which limits the number of plant and animal species that can live there. According to the above, the correct answer is C. The climate is harsh, which limits the number of species that can live there.
