Answer:
78 percent
Explanation:
The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
Answer:
1.33 m/s
Explanation:
The formula for Kinetic Energy is given as:
Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.
Re-arranging the above equation and isolating v, we get
Putting values in this equation, we get:
Thus, the object is moving with a velocity of 1.33 m/s
The mass would be 0.5kg
To find the mass of an object with acceleration and force would be
m = f/a

The nervous system conserves energy, while the sympathetic nervous system consumes energy.
<h3>What is the nervous system?</h3>
The nervous system is an organ system that coordinates the activities of muscles, monitors organs, constructs and processes data received from the senses and initiates actions.
The nervous system can either be the following;
- Sympathetic
- Parasympathetic
The sympathetic nervous system is a part of the autonomic nervous system that raises blood pressure and heart rate, constricts blood vessels, and dilates the pupils when under stress.
On the other hand, the parasympathetic nervous system is one of the divisions of the autonomic nervous system, based between the brain and the spinal cord, that slows the heart and relaxes muscles.
This suggests that the parasympathetic nervous system conserves energy because it slows the heart while the sympathetic nervous system consumes energy.
