Answer:
A property that changes if the amount of substance changes
Explanation:
An extensive property is a property that depends on the amount of matter in a sample.
Final answer:
An extensive property changes if the amount of substance changes. For instance, mass and volume are extensive properties as they would vary depending on the amount of substance.
Explanation:
An extensive property is a property that changes if the amount of substance changes. For example, mass and volume are extensive properties. If you have two separate samples of a substance, each with a different amount, their mass and volume would be different. On the other hand, the melting point or boiling point of the substance, which are examples of intensive properties, would not change regardless of the amount of substance.

Answer: weight helps gravity
Explanation
for example, when you outside with the wind blowing, your weight dont let you get carried away.
Final answer:
Technologies helping humans cope with gravity include methods to simulate weightlessness for training and entertainment, and prospective technologies suggested by general relativity theories like the gravity-based time machine. Studies on the gravity response in plants can also help sustain long-term space missions.
Explanation:
There are many technologies and methods designed to help humans cope with the effects of gravity. For example, astronauts on the International Space Station (ISS) experience gravity but appear weightless because they are in constant free fall around the Earth. This is akin to the principle of equivalence, which states that falling around the Earth creates the same effects as being far off in space, away from all gravitational influences.
Training facilities, like NASA's Vomit Comet, provide an environment for astronauts to experience a state of near-weightlessness or free fall, preparing them for their missions in space. Moreover, innovations such as underwater filming, wire stunts, and computer graphics can also mimic the appearance of weightlessness, as seen in movies such as Gravity and The Martian.
Also, findings related to gravity and time machines in general relativity suggest that it might be possible, in theory, to move through time using gravity. Meanwhile, studies on how plants respond to gravity might contribute to long-duration space missions by regenerating the atmosphere, purifying water, and producing food.
