In vacuum, going at 2.99×10^8 m/s.
FREQUENCY is the number of complete waves that pass a given point in a certain amount of time.
Good luck :)
The air flows slower in a bigger space. The air in a small space hit each other heating up, and move faster and faster. is that what your asking?
The correct answer is C. Velocity is a vector and requires a direction.
Explanation:
In physics both speed and velocity are used to study the motion of a body; however, they are slightly different. In the case of speed, this describes the rate of change in position based on distance and time, because of this, speed is based on a magnitude or quantity. On the other hand, velocity is a vector because it does not only includes a change of position but the direction of motion usually based on a specific location reference.
Considering this, it can be concluded the difference between speed and velocity is that "velocity is a vector and requires a direction" because velocity includes both the distance and time (speed) along with the direction while speed focuses only on time and distance.
