They are both used to observe and describe matter.
Answer:
Phosphorus
Explanation:
Phosphorus needs 3 electrons to complete its outter most shell of electrons
The distance between the plates is 7.1 * 10^-7 m
<h3>What is the distance?</h3>
The capacitor is a device that is used to store charges. The capacitor always has a dielectric that is placed between the capacitors that separates them.
Given that;
C = εoA/d
C = capacitance
εo = permittivity of free space
A = cross sectional area
d = distance apart
Cd = εoA
d = εoA/C
d = 8.8 * 10^-12 * 8.89 * 10^-4/1.11 * 10^-8
d = 7.1 * 10^-7 m

Answer:
The purpose of step 1 is to induce magnetism into the needle, so that it retains magnetism and behaves as a magnet after the process.
Explanation:
The method of production the needle magnet in the procedure is the single stroke. This process involves a continuous stroking of a magnetic object (e.g needle) repeatedly for a period or number of times with a permanent magnet. Thus, when the permanent magnet is removed, the object retains magnetism, and behaves like a magnet.
The importance of the stroking process is the turn a magnetic object to a magnet by inducing magnetism into it.
It's easier for you to solve these than to try and read my solutions if I solve them.
Use this magic formula:
(period) · (frequency) = 1
If you handle the magic formula carefully and correctly, you can get these facts out of it:
-- Period = 1 / frequency
-- Frequency = 1 / period
Use the first one to solve #1.
Use the second one to solve #2.
