Look at the table for energy used in activities. James goes walking for 1.5 hours a week and running for 0.5 hours. James has a mass of 65kg. How much extra energy will he need a week in order to go running and walking?

Answers

Answer 1

The extra energy needed by James in a week is 1950 joules.

Dimensionally speaking, the energy ([tex]E[/tex]) , in joules, need by a person while doing an activity is defined by the following expression:

[tex]E = m\cdot t\cdot c[/tex] (1)

Where:

[tex]m[/tex] - Mass, in kilograms.[tex]t[/tex] - Time, in hours.[tex]c[/tex] - Energy index, in joules per kilogram-hour.

The extra energy needed by James is the sum of the energy spent both by running and walking:

[tex]E = 65\,kg \times \left(1.5\,h \times 10\,\frac{J}{kg\cdot h} + 0.5\,h \times 30\,\frac{J}{kg\cdot h} \right)[/tex]

[tex]E = 1950\,J[/tex]

The extra energy needed by James in a week is 1950 joules.

Why are the average temperatures in the middle of the United States warmer than the coasts? I NEED THIS ANSWER ASAP!

Answers

Answer:

Here

Explanation:

The environment of the United States shifts because of changes in scope, and a scope of geographic highlights, including mountains and deserts. By and large, on the central area, the environment of the U.S. becomes warmer the further south one ventures, and drier the further west, until one arrives at the West Coast.

Being near huge amounts of water, such as oceans, lowers the temperature of a site that is just as close to the equator as one without any. As a result, temperatures in the middle of the country rise far more than in coastal states.

identify the structure that regulates the amount of light entering the posterior segment of the eye.

Answers

Iris is the structure that regulates the amount of light entering the posterior segment of the eye.

The colored disc-shaped membrane found in the eye of humans and various animals is called the iris.

The pupil appears in the center of the iris: an opening that allows light to enter.

It is located behind the cornea, constituting a separation between the posterior chamber and the anterior chamber of the eye.

It helps to dilate or contract the pupil to allow more or less light to enter the eye.

Therefore, we can conclude that iris is the structure that regulates the amount of light entering the posterior segment of the eye.

A patent meant that no one else could claim that they had invented the telephone. Bell began working with telegraph machines. He wanted to send sound waves over a telegraph wire using a multi-reed system. It could be tuned like a harp. He did not have the equipment to experiment with his idea.Then Alexander met Thomas Watson. Watson was an electrical designer who became Alexanders assistant. They found that only one reed was needed to make sounds. Together the men built a telegraph that could send sounds. The waves did not sound like voices yet. On March 7, 1876, Bell received the patent for his invention.Bell kept working on the telephone. On March 10 of the same year, Bell and Watson made the telephone work. Bell and Watson then improved the telephone. In August 1876, Bell sent a telegram to a town five miles away. People in the telegraph office could hear voices on the telephone. The next day, Bell strung a telephone wire across six miles. The message sent over the telephone wire could be heard clearly. This showed that the telephone worked over long distances.Bells invention became popular very quickly. By 1886, 150,000 people in the United States owned a telephone. Alexander Bell continued to invent for the rest of his life. The telephone remains the most important of his inventions.Which detail from the third paragraph is most important to include in a summary of the passage?A.
