Explanation:
a. The velocity of the wind as a vector in component form will be represented as v vector:
b.The velocity of the jet relative to the air as a vector in component form will be represented as u vector
c. The true velocity of the jet as a vector will be represented as w:
d. The true speed of the jet will be calculated as:
e. The direction of the jet will be:
<span>its kinetic energy is 7350kJ
</span>
Kinetic energy is given as =
Now, m = 12 gms = 0.012 kg
And, velocity = 35 kilometers/second = 35000 m/sec
Kinetic energy is given as =
![\frac{1}{2} 0.012 kg * 35000*35000 m/[tex] s^{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%200.012%20kg%20%2A%2035000%2A35000%20m%2F%5Btex%5D%20s%5E%7B2%7D%20)

A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person's vocal chords. The vibration disturbs the particles in the surrounding medium; those particles disturb those next to them, and so on. The pattern of the disturbance creates outward movement in a wave pattern, like waves of seawater on the ocean. The wave carries the sound energy through the medium, usually in all directions and less intensely as it moves farther from the source.

YESSS. my education went down hill since the pandemic :(
Explanation:
There is a difference between dragand friction. Friction is relatively constant at different velocities whiledrag increases with speed. Forexample, when you rub your hands together at different speeds, the force of friction remains the same although the heat generated will vary.
