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:
The type of physical activity you choose lies at the heart of the FITT principle. All other aspects of the model revolve around it. Generally speaking, cardio and resistance training are the two most common types of exercise. The former includes running, swimming, bike riding, and hiking.
Explanation:
Answer: False
Explanation:
Physical activity involves the movement of the body. Physical activity is important as it helps in the improvement of ones brain and also provides strength to the bones.
It should be noted that physical activity must not be strenuous to be effective. For example, one can take a walk or rather than using an elevator, one can take a stair. This is a physical activity and it's not stressful.
