Answer:
iv. There is no force of gravity acting upon orbiting astronauts.
2. it measures the mass
Explanation:
A logical fallacy occur in step iv
There is actually force of gravity upon the orbiting astronauts. Gravity exist in space. there is an upward and downward forces that keeps the body stable.
1,ii,iii are correct logical statements
2.What does the scale measure? ___________________ If a scale does not technically measure your weight, then why is it often used to measure your weight?
The scale measures ones mass.
Mass is the quantity of matter in a body. Matter is anything that has weight and occupies space. Assuming we are to measure the weight of ones body we will need to be hanged in the air and take measurement with the aid of a spring balance.
At this instant, the force of gravity will be acting on the body(that is one will experience the earth's gravitational pull to the earth's center)
Force is the pull or push on an object. F=mass * gravity
Force is also that which tends to change a body's state of rest or uniform motion on a straight line.
Newton's second law of motion states that the force applied is directly proportional to the rate of change in linear momentum
Answer:
When exercising for muscle strength, you should isolate the muscles to be strengthened; carry out the correct motion fully in a smooth and controlled manner without other muscles compensating. People tend to compensate when they are tired, which is when other muscles take over for the fatigued muscles. When you are exercising, be mindful of this tendency and make adjustments in resistance in order to isolate the appropriate muscles. Whenever possible, exercise a joint through its full range of motion so as to work the entire muscle and not to use too much weight or resistance during the end of a motion.

<span>Alternating between running and walking is important, especially if you're not a professional runner. You should be walking from time to time to recover a bit from the strain that the running put on you, but not too much or your body starts to cool down and then you have to work all over again or you might lose energy.</span>
