Answer:

Explanation:
In order to find the force between the two electrons, we need to use Coulomb's law. In its scalar form, the law is given by:

Where:

The electric charge of an electron is a known constant given by:

So:

Therefore, replacing the data provided in the Coulomb's law equation:

The correct answer is "wavelength".
In fact, this is exactly the definition of wavelength: in a wave, the wavelength is defined as the distance between two succesive crests or two successive troughs, therefore the correct answer is
D) wavelength.
The dogs centripetal acceleration is 2.4 meters/second^2
Answer:
P = 5880 J
Explanation:
Given that,
The mass of a person, m = 60 kg
The height of the stairs, h = 10 m
We need to find the gravitational potential energy of the person. The formula is as follows :

Substitute all the values,

So, the required gravitational potential energy is equal to 5880 J.
