Answer:A wave is a disturbance that moves along a medium from one end to the other. If one watches an ocean wave moving along the medium (the ocean water), one can observe that the crest of the wave is moving from one location to another over a given interval of time. The crest is observed to cover distance. The speed of an object refers to how fast an object is moving and is usually expressed as the distance traveled per time of travel. In the case of a wave, the speed is the distance traveled by a given point on the wave (such as a crest) in a given interval of time.
Explanation:
Y=mx+b so slope is always M which in your case is 9/5
Answer:
There is an attractive force call gravity
Explanation:
The reason the moon's inertia doesn't make it continue in a straight line is due to the attractive force of gravity and the reason the moon and earth's gravity doesn't make them collide with each other is due to the moon's inertia. To understand this phenomenon imagine that you have a ball tied to a rope, you keep the rope with one hand and with the other you push the ball so it can move freely; the ball, like the moon, has velocity, but the ball can not move in a straight line because the rope doesn't allow it, in our hypothetical scenario the rope is like the gravity that traps the ball in an 'endless' circle.
Note: The rope and the ball are a hypothetical case, it helps us imagine the phenomena but the forces involved are different than in the case of the moon.
Las vegas NV is one example
Answer:
Stars
Explanation:
I think back then that ancient civilizations trusted the night sky or more advanced ones used compasses before maps were made and trusted. The Mayans I believe practiced astrology (astronomy?) and we still do know because the sky is always there for us.
