Answer:

30 CM one because the light gathering power will be better

Explanation:

Based on the information provided within the question it can be said that in this scenario the best option that you can choose from would be the 30 CM one because the light gathering power will be better on that one as opposed to the 20cm one. In telescopes the larger the lens, the clearer the image will be  as it allows more light to enter and cause the image to be sharper.

The worldwide use of cleaner energy sources could lead to which of the following results?
Leni [432]

The second alternative is correct (B).

The economic matrix in force in the world is based on the burning of fossil fuels, mainly petroleum, which releases amounts of CO2 and other gases in the ozone layer.

The acid rain is due to the exaggerated amount of products from the burning of fossil fuels released into the atmosphere. That is, human activities are mainly responsible for this phenomenon of acid rain.

Thus, the change to a clean energy matrix, using solar, wind and other energy, can result in a decrease in the phenomenon of acid rain.

How does the study of motor behavior differ from the psychology of sport? 2. Explain the differences between motor learning and
In-s [12.5K]

Answer:

1. <u>The study of motor behavior</u> involves the analysis of principles and laws of physics in human and animal biology to understand how living beings move.

<u>The psychology of sports</u> is responsible for analyzing the psychological factors that influence the athletic performance of athletes, and how these can improve their professional performance.

2. <u>Motor learning refers to the process of acquisition of motor skills permanently thro</u>ugh the process of practice and experience. For example, learn to ride a bicycle.

While <u>motor control</u> is the biological process that involves the coordination between the nervous system and the muscles to carry out a movement.

In order to carry out the motor learning, a motor control must be carried out beforehand.

3. It is important because motor learning is done through constant repetition, this drives to optimizing motor control. However, throughout life, motor control deteriorates due to the aging of the nervous system and the neuronal process, making it more difficult to learn new skills or perform skills already learned.

To avoid the loss of motor functions the exercise of the skills that already learned should be continued, driving to a healthier life.

4. I will choose tennis as a sport, high school education, and age; young people between 15 and 17 years old.

Tennis is a sport that requires the coordination of eye-hand, and hands-feet. It also requires muscle strength in the upper and lower extremities.

The age group should already have a certain level of motor learning that allows it to perform the required movements, these should be reinforced so that it would establish a daily hour of exercises to reinforce the motor control that is needed.

In addition to the exercise time, I would establish one more daily hour of specific exercises for proper movements of tennis.

Due to the age of the youth, they are more vulnerable to social or personal pressures, so my plan would involve weekly individual meetings so they can express how they feel about their performance and analyze individual changes to their work plans.

5. An example could be the practice of volleyball in a covered place with an artificial environment or practicing it outdoors. If the athlete gets used to the weather conditions he may experience when playing outdoors, for example; the sun, the heat and even the wind, when playing in a roofed environment where the weather conditions are not a problem, it will be easier to play. If it were to the contrary, and he got used to playing in a covered environment, it would be more difficult to play outside.

This is because motor learning is conditioned by the level of effort required to do it.

If I were a coach, I would initially start in an intermediate training environment and gradually increase the difficulty for the athletes to be prepared to play in any kind of environment.

I hope this information can help you.
