A single electron has a charge of
Therefore, if we have an excess of
electrons, the total net charge will be the product between the charge of a single electron and the total number of electrons in excess:
The speed of sound is 340.29 meters per second.
Knowing that, we can calculate how high this cliff is by 340.29 * .4
The cliff is 340.29 * .4 = 136.12 meters
Answer:
The car travel 2.52 m
Explanation:
This problem gives us the time and speed of the car with the echolocation system, and they ask us for the distance traveled, we can use the report motion equation.
Let's start by calculating the relative speed of the two cars, which in this case is the initial mass because the second vehicle is at rest.
v = d / t
d = v t
d = 14 0.18
d = 2.52 m
The car travel 2.52m
Decibel - the decibel is a relative unit of measurement equal to one 10th of a bel
