Answer: Longitudinal waves
Explanation: For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal. Longitudinal waves are waves in which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport

<h3>
The Speed and the Velocity of a Particle in a Circle</h3>
The speed of a particle is a circle will always be constant while the velocity will not. That is, velocity varies.
Given that a jogger jogs around a circular track with a diameter of 275 m in 14.0 minutes. First convert the minutes to seconds
Given parameters are;
- Time t = 14 minutes = 14 x 60s = 840 s
Speed V = 2πr ÷ t
V = ( 2 × π × 137.5 ) ÷ 840
V = 863.9 / 840
V = 1.028 m/s
Therefore, the jogger's average speed 1.03 m/s approximately

Answer:
Needs, Wants
Explanation:
Needs are necessary, wants are not
Let's convert the speed of the winds into SI units.
We know that
1 miles = 1609 m
1 hour = 3600 s
So, the velocity written in m/s is
