Write the different between the fall of a parachute on earth and its fall on the moon?on what condition does a body have free fall?

Answers

Answer 1
Answer:

Answer:

Shown from explanation

Explanation:

You have heard that expression what ever goes up must come down that's usually used to mean when you throw an object up, it comes down on its accord. This is due to a force on the earth that occurs in nature known as gravity.

So when an object falls under this influence it's said to fall freely.

Note not all heavenly bodies have gravitational pull, from experience by scientists who went to the moon they found out whatever goes up keeps flying endlessly so in that case an external force is needed to keep objects in the moon on ground level.

Hence the parachute falls on earth freely without an external force but on the moon it must fall with an external force inputed on the parachute system.

This means in the earth we have free fall but in the moon no such thing exist. So a body falls freely when there is gravity.

What makes a hypothesis testable

Answers

A hypothesis is testable when you can create an experiment to study the proposition contained within the hypothesis. For example, the hypothesis ‘Santa travels slower than a unicorn’ is testable in theory by measuring the speeds of both, but it is not truly testable because neither exists in reality.

Which statement best describes the relationship between forces?a.Magnetic and electrical forces are the most alike because they are both caused by positive and negative charges.

b. Gravitational and magnetic forces are the most alike because they are both types of charges that occur in nature.

c. Nuclear and magnetic forces are the most alike because they are both related to mass and weight.

d. Strong nuclear force is most like electric because they are both related to distance.

Answers

The statement which best describes the relationship between forces is the last option represented above d. Strong nuclear force is most like electric because they are both related to distance. According to the general characteristics, it can't be caused by positive or negative charges and does not relates to mass and weight.

Answer:

d) strong nuclear force is most like electric because they are both realted to distance.
