In order to achieve and maintain physical fitness, exercise intensity should be , anywhere between 70%-85% of the maximum heart rate of a person.

Anywhere below this, and physical exercise won't be that effective. Anything more than this and it might be dangerous for the human body.

70-85% is the optimum value

To achieve and maintain physical fitness, exercise intensity should be 70% to 85% of the maximal heart rate.

When we do an exercise, our heart rate increases. And when heart rate increases, the body starts to burn energy that is stored in the body in the form of fats. So if anyone wishes to burn out calories/fats, the exercise intensity should be 70% to 85% of his maximal heart rate. In this way the fats would burn and the goal of fitness is achieved.

oksian1 [2.3K]

Answer:

The correct answer is (B) discussing explanations for an unexpected scientific finding.

Explanation:

A serendipity is a discovery or a fortunate, valuable and unexpected finding that occurs accidentally, by chance or by destination, or when a different thing is being sought. It can also refer to the ability of a subject to recognize that he has made an important discovery even if it is not related to what he is looking for. Serendipities are frequent in the history of science. There are also cases of serendipity in literary works, when an author writes about something he has imagined and is not known in his time, and it is subsequently shown that this exists as defined by the writer, with the same details. It should not be confused with anticipation or science fiction, where much more generic inventions are advanced than almost everyone thinks they will probably exist one day.

When the price of candy bars is $1.00, the quantity demanded is 500 per day. When the price falls to $0.80, the quantity demande

Wittaler [7]

Answer:

The demand for candy bars is inelastic

Explanation:

The midpoint rule calculate the price elasticity of demand as percentage change in quantity divided by the percentage change in price:

<u>% change in quantity </u>

$\frac{Q_2-Q_1}{ \frac{Q_2 + Q_1}{2} } \times 100$

The quantity demanded increased from 500 to 600. We have

$Q_1 = 500 \: and \: Q_2 = 600$

$\implies \frac{600 - 500}{ \frac{600 + 500}{2} } \times 100 \\ = \frac{100}{ \frac{1100}{2} } \\ = \frac{100}{550} \\ = \frac{2}{11}$

<u>% change in price</u>

$\frac{P_2-P_1}{ \frac{P_2 + P_1}{2} } \times 100$

The price changed from 1 dollar to 0.8 dollars.

$\frac{0.8 - 1}{ \frac{0.8 + 1}{2} } = - \frac{2}{9}$

Price elasticity if demand is

$\frac{ \frac{2}{11} \%}{ - \frac{2}{9} \%} = - \frac{9}{11} = - 0.82$

The negative sign tells us that there is an inverse relationship between price and quantity demanded.

Since 0.82 is less than 1, the demand for candy bars is inelastic

alex41 [277]

The answer is psychological.

In the given scenario, Ed has an almost-new economy car, but he wants a Ford Mustang because he thinks it would be exciting to own one.

Since Ed already has a car that works, he does not have a functional need for a car.

Therefore, a choice to purchase a sports car would represent a psychological need.

This shows perhaps the car makes him feel cool or adventurous.

So, this demonstrates that he will be fulfilling his mind. Consequently, fulfilling his psychological need.

Hence, If he decides to purchase a sports car such as the Mustang, he will be primarily fulfilling a psychological need.
