Answer:
Negative
Explanation:
If a negatively charged object is used to charge a neutral object by induction, then the neutral object will acquire a positive charge. And if a positively charged object is used to charge a neutral object by induction, then the neutral object will acquire a negative charge:
We have a neutral sphere
1) Electrons are attracted to the positive charge
2) Electrons enter the sphere from ground, attrated to the + charge in the sphere
3) The sphere has an excess of e- having entered from the ground
4) Electrons redistribute uniformly
Not only in converting temperatures I think, we always use significant figures every time we want to make some experimental report using the exact data from our experiment. If that isn't experimental report ( some exercise/questions from your textbook) it's not necessary
The answer is apparent weight is zero.
You are still accelerating downwards at 9.8m/s^2 (if you are on Earth).
You still are being affected by the Earth's gravity.
Not all because of the previous two statements.
Not none because apparent weight is zero as you are falling.
Answer:
the net electric charge of the iron atom is 2.24 × 10⁻¹⁸ C
Explanation:
Given the data in the question;
we know that neural iron atoms should have same number of protons and electrons i.e 26 and 26 but in the sun's atmosphere, many of their electrons stripped away.
so; we have 26 protons and 12 electrons, meaning ( 26-12=14) 14 electrons have been stripped away.
when we loss electron, we gain positive charge
so, the Net charge of the iron atom of with 26 protons and 12 electrons will be;
q = 26 ( proton charge) + 12( electron charge )
we know that; a singular proton has a charge of 1.6×10⁻¹⁹ C
protons carry negative charge while electrons carry negative
we substitute
q = 26 ( 1.6×10⁻¹⁹ ) + 12( -1.6×10⁻¹⁹ )
q = 2.24 × 10⁻¹⁸ C
Therefore, the net electric charge of the iron atom is 2.24 × 10⁻¹⁸ C
