Answer:
In physics, motion is the change in the position of an object over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. The motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame.

When the sun's rays strike Earth's surface near the equator, the incoming solar radiation is more direct (nearly perpendicular or closer to a 90˚ angle). Therefore, the solar radiation is concentrated over a smaller surface area, causing warmer temperatures.
B would be an example of vaporization (liquid to gas).

A is an example of deposition (gas to solid); C is an example of condensation (gas to liquid); and D is an example of condensation, deposition, or freezing—depending on the type of cloud.
Answer: 30
Explanation: it is 30 meters per seconds
Answer:
Explanation:
Speed is the distance covered over the time taken to do so.
s = d/t = 45 m / 3 s = 15 m/s
