A:a diver jumping Off a diving Board And falling to the swimming pool below
Answer:
Your answer doesn't provide that much evidence that much. But, I try to help you find the answer. I think your answer is the number of cycles per second perceived by the human ear. Well, Pitch is basically our sound of our voice. Sometimes, Our voice can even go 'higher' or 'lower'. Let me give you a example. If we screen our voice go higher than before and sometime it can even pitch. And, Sometime when we talk lower our voice give us a lower tune.
Good Luck!!~

Answer:
Either B or D. The answer itself is 2.
Explanation:
The equation for the kinetic energy would be 1/2*mv^2.
When m is doubled, we can plug in 1 and 2 to compare our answers.
Plugging in 1 for mass would give us the answer 1/2*v^2.
Plugging in 2 for mass would give us v^2. This means that the velocity was multiplied by 2, meaning that the answer is it is multiplied by 2.
I am not sure which answer is correct since there seems to be two answer choices with 2 in it, but the answer is either B or D (I will call it ABCD because I do not want to cause confusion by saying 2 multiple times).
It is the second provided answer.
Speed is the change in distance over time; velocity is speed plus direction.
Answer:
Polarized sunglasses
Explanation:
Polarized sunglasses are comprised of polarized lenses which have a special type of filter that can block the strong reflected light emitted from the sun. It also helps in decreasing the beam of light and eventually reduces the discomfort during the bright sunlight. It reduces the eye strain to see the objects clearly and visibly.
These sunglasses are mostly used while driving and protects our eyes from the harmful incoming solar lights and enables a person to observe the path clearly without any disturbance.
