Answer:
27 . 10^-7 or 27/1000
Explanation:
We use the Coulomb Law
k = Coloumb Constant
q1 and q2 are the charges
d is the distance between the spheres

Answer:
The electric force will be 0 N
Explanation:
From the question we are told that
The magnitude of the charge is
Generally from Coulombs law the electric force between two charges is mathematically represented as
Here r is the distance of separation between that two charges.
Now from the question we are told that the charge is far away from any other charge hence we can say that the distance between the charge and any other charge is
So
=>
Hence the electric force will be 0 N
Answer:
Explanation:
Given
Required
Determine the speed of B w.r.t A
The question implies that, we determine the relative velocity of B w.r.t A
Because both trains are moving towards one another, the required velocity is a both trains:
This is shown below:
Answer:
The details of bands is given in explanation.
Explanation:
The electromagnetic waves are differentiated into different bands based upon their wavelengths and frequencies. The names of different bands are as follows:
1. Radio Waves
2. Micro Waves
3. Infra-red
4. Visible light
5. Ultra Violet
6. X-rays
7. Gamma Rays
<u>The frequency of every region or rays increases from 1 through 7</u>. The <u>energy of rays also increase from 1 through 7</u>. Since, the wave length is inversely related to energy and frequency, thus the <u>wavelength of rays decrease from 1 through 7</u>.
A detailed information of the bands is provided in the picture attached.
