The correct answer for the question that is being presented above is this one: "biosphere, atmosphere." The earth's four main spheres continuously interact to support life and balance Earth's materials. When plants absorb carbon dioxide for photosynthesis, <span>it is an example of biosphere and atmosphere sphere interaction.</span>
It shows that the airplane covers equal distance in equal time interval, that's it has a straight line from the origin.
The plane is moving at uniform speed.
<u>Answer;</u>
<em>D. The object’s weight changes, but its mass stays the same.</em>
<u>Explanation;</u>
- Mass is the amount of matter in a object, which is measured in kilograms. Mass of an object is measured using a beam balance. It is important to note that the mass of an object or a body remains constant, and does not vary from one place to another. For instance the mass of a person on the moon will be the same as when the person is on the earth surface.
- Weight on the other hand is the measurement of gravitational pull of an object. weight is measured using a spring balance and measured in Newtons. Weight varies from one place to another depending on the gravitational pull of a given surface.
