is the charge
<u>Explanation:</u>
The electric fields can be defined as the ratio of electric forces per unit charge.
---------> eq 1
The electric field differs from many quantities such as mass, forces, and speed. The electric field is not a property of a particular object, but a property of a given point in space. All electric charges form an electric field and we can analyse the value (size and direction) of this field at any point in space around the distribution of the charge.
The simplest formula for an electric field is that produced by a point charge:
------> eq. 2
Where,
q - Charge
r - Distance of separation from the charge
k = the Coulomb constant ( )
If the charge is negative, the field is radially inward; if the charge is positive, it is directed radially outward.
Here, given data:
r = 83.9 m
E = 46 N/C
We need to find q.
Substitute the given values in eq 2, we get
Answer: W is nucleus, Y is Neutron, Z is proton, and X is electron
Explanation:
Answer: leftover radiation from the big bang
Microwave background radiation is a form of electromagnetic radiation that is present in the whole universe and completely fills it.
Its frequency belongs to the microwaves range and is one of the main demonstrations of the of the Big Bang theory model.
It is important to note the Big Bang occurred 400,000 years before the events related to the microwave cosmic radiation, this means the Big Bang occurred first.
