There is little winds in these areas because they are in a low-pressure area around the equator. The area is also known as the Intertropical Convergence Zone.

For people to associate their food, not with unhealthy lifestyles but au contraire with lifestyles that Evoque nutrition-consciousness.

As we now, classical conditioning happens thanks to an association. In the olden days, doctors used to advertise cigarettes, for people to see cigarettes as a healthy habit. By associating doctors and cigarettes people will assume that smoking wasn't that bad because a Doctor who is a person concerned with health was recomending them.

The same principle applies here.

Seeing an athlete recommending a certain brand of fast food would make people think that maybe, that particular brand is healthier than others.

Guide Questions: 1. Why should you take care of the respiratory and circulatory system?

GuDViN [60]

Answer:

1. Taking care of these systems would ensure smooth cellular metabolism.

2. It would reduce the risk of heart diseases.

3. It would help in the maintenance of the right pH for the blood.

4. It would allow for the easy removal of the waste products from the body.

Explanation:

The respiratory system refers to the series of processes that begin with the inhalation of air and its movement across the blood vessels and eventual discharge from the body. Oxygen which is a very important gas needed to sustain life is inhaled during respiration. It is also circulated through the circulatory system to the cells and tissues that need it.

Taking care of these systems through exercise, rest, and eating the right foods will protect us from diseases that affect them such as Heart attack. Cells would also function well and not die easily because they can access the oxygen needed for them to thrive. The right balance of these gases would also ensure that the proper pH of the body is being maintained.

A basketball is dropped from the edge of a cliff at the same time that second basketball is thrown upward from the ground. When

pentagon [3]

Answer:

The collision occurs at a height of 1/3 of the total height of cliff.

Explanation:

The situation is represented in the attached figure:

For the stone dropped from top of cliff we have

Initial velocity of drop= 0 m/s.

Now the time at which it attains a velocity of 2v is obtained from first equation of kinematics as

$v_{f}=u_{i}+gt\\\\2v=0+gt\\\\\therefore t=\frac{2v}{g}$

Thus the distance it covers in this time can be calculated using third equation of kinematics as

$v_{f}^{2}=v_{i}^{2}+2gh\\\\(2v)^{2}=2gh_{1}\\\\\therefore h_{1}=\frac{2v^{2}}{g}$

For the stone thrown upwards the velocity at collision is give as 'v' thus the velocity at which it is thrown upwards can be calculated by first equation of kinematics as

$v=v_{i}-gt\\\\\therefore v_{i}=v+gt\\\\v_{i}=v+g\times \frac{2v}{g}\\\\\therefore v_{i}=3v$
