What are the disadvantages of using wind and solar energy?

Answers

Answer: The Wind Fluctuates. Wind energy has a similar drawback to solar energy in that it is not constant. Wind Turbines Are Expensive. Although costs are reducing, wind turbines are still very expensive.

1: The Wind Fluctuates, wind speed does change. This can cause serious problems for the efficiency of a wind turbine.
2: Wind Turbines Are Expensive, wind turbines are still very expensive. If deemed adequate, a wind turbine then needs to be purchased, transported and installed. All of these processes contribute to the high cost of buying and installing wind turbines.
3: Wind Turbines Pose a Threat to Wildlife, wind turbines still contribute to mortality rates among bird and bat populations.
4: Wind Turbines Are Noisy, You can sometimes hear them from hundreds of meters away depending on the wind direction. Combine multiple wind turbines with the right wind direction and the audible effects can be much greater.

Answers

Answer:

the change in internal energy of the gases is  -3.0924 KJ

Explanation:

The computation of the change in internal energy of the gases is as follows;

Given that

Q = -3.1 KJ

= -3100 J

It is negative as the heat is lost from the mixture

And,

W = + 7.6 J

It is positive as the work is done in the mixture

Now we use the following equation

Delat E = Q + W

= -3100 J + 7.6 J

= -3092.4 J

= -3.0924 KJ

Hence, the change in internal energy of the gases is  -3.0924 KJ

Answer: Different types of plants use different types of carbon fixation as adaptations to varying conditions.

Explanation: Different plants have evolved different types of carbon fixation methods as an adaptation towards varying conditions

Different types of plants use different types of carbon fixation as adaptations to varying conditions. The statement is True.

What is Carbon fixation?

Carbon fixation is the process by which inorganic carbon, from the atmosphere, is attached to an organic compound, usually a carbohydrate. This process is catalyzed by the enzyme RuBisCO, the most abundant enzyme on earth.

Carbon fixation is a cornerstone when it comes to the process of photosynthesis. Without carbon fixation in the Calvin cycle, photosynthesis would not be able to occur and plants would not be able to make their own food.

Therefore, Different types of plants use different types of carbon fixation as adaptations to varying conditions. The statement is True.

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, the given statement is true.

What is matter?

Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.

Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.

So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Cold, dry air against warm air creates a cold front, and visa versa warm air pushes against cold air its a warm front.

Therefore, the given statement is true.
