The invisible form is water vapor that is microscopic and found all around us. When the air is really hot you can see this water vapor above ground as if it's moving. The visible form is either water droplets that fall down as rain, or it's the clouds that are basically a form of moisture that is iced up because it's very cold so it condensed and formed a cloud.
Answer:
A and C
Explanation:
drag (the area of lower air pressure behind the car when moving) and mostly air resistance (the work to push the air in front of us away to move through - the faster we go, the stronger the air resists to move aside).
Answer:
Liquids are more dense than gases, but less dense than solids, so sound travels 2nd fast in liquids. Gases are the slowest because they are the least dense: the molecules in gases are very far apart, compared with solids and liquids.
Explanation:
Answer:it is the exact location of something.
Explanation:
Gravitational force is an example of at-a-distance force
Option: C
<u>Explanation:
</u>
Force has both direction and magnitude it is a "vector" quantity. Force is defined as pull or push of an object resulting it to interact with two objects. There are 'Contact forces' and 'At-a-distance forces'. If two interacting objects are not in a physical contact with respect to each other the force is exerted between these two objects called 'at-a-distance' forces. This type of forces consists gravitational forces. Some of the examples of the 'at-a-distance' forces are electrical and magnetic.
