I think the first question is talking about the ionic compound Sodium sulfide and it’s formula is Na2S.
And for the second question, i’m pretty sure it’d be a positive charge
The magnitude of the acceleration is equal to 31.5
<u>Given the following data:</u>
To determine the magnitude of the acceleration:
In Science, the acceleration of a particle in a <u>circle</u> or circular track is known as centripetal acceleration.
<h3>How to calculate
centripetal acceleration.</h3>
Mathematically, centripetal acceleration is given by this formula:
Substituting the given parameters into the formula, we have;
Centripetal acceleration = 31.5

Answer:
Explanation:
Formula
Force = mass × acceleration
147N =? × 9.8 ms2
M =
M = 15
Double Check
15 X 9.8
147N
Hope this helps!
Answer:
I hope this answer is correct
Explanation:
The mechanical advantage of a machine is 4. Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
