Please write a one page paper about how a dog whistle works! Will give brainlilest! Requirements:
Must be able to explain your topic of interest

Must be able to use some of what you have learned about sound (pitch, frequency, order of vibration etc) to help explain how the science of sound causes the phenomenon you are researching

At the end of the paper you must have listed at least 2 different websites that you used to help explain your area of study.
Must include name of web page
web address
author of the article or website.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
