Does string theory say that an electromagnetic field or a gravitational field is caused by particles such as gravitons?

What are all of these particles called in general(including gravitons)?

So does this mean energy is used up when creating an electromagnetic field?

What is the formula for percetage increase? For example I'm trying to calulate the origional number. Number is $108.90, it increase 8.9%, how do I get back to the origonal number which is $100? What is this formula.

Or once again. Number is $136.13, increase 8.9% how do I get back to $125?

How do I know going backwards what the old number was after increasing 8.9%

Thanks!

Please help me find the proof on this matrix equivalence theorem.

Two mxn matrices A and B are equivalent if and only if B=PAQ for some nonsingular matrices P and Q.

I am a Chemical Engineering sophomore but I'm looking for an internship position in both chemical engineering and science fields (chemistry, physics, biology, environment, laboratory, research etc.)
I desperately spent a lot of time to find one using job search machine but failed. I know that many internship positions are not posted online. So, I hope someone here can help me with the information
I'm looking for a PART-TIME SEMESTER INTERNSHIP, not a summer internship. Also, I can start working immediately and ACCEPT AN UNPAID INTERNSHIP if the job can help me gain hand-on experience. It will be a lot of help if you can provide me a direct link to the internship page.
Thanks in advance and I'm looking forward to hearing from you,
Have a nice day,
Hopeless guy,
Minh
