Understood. I will keep that in mind during the examination. However in the exercises they will usually give out answers with a lot of digits and I usually put a lot of digits too just to ensure I don't fall out of that 5% range. Thank you for your advise

Understood. Thank you

Understood. I'll have the homework coordinator look at it in a few days and focus on the others for the time being. Thank you.

Yes over here The answer wants it in Ns or kgm/s

I'm sorry. Its an online homework that accepts a range of ±5% of the actual value. And usually the actual value given has lots of decimal places. I put lots of decimal places in the answer just so I don't accidently fall out of the range. So any value I type as long as it is within the range...

The answer to the question has a ±5% to the answer, so even if the answer is 1.9E-24, my answer of 1.8842808E-24 should be accepted. So that rules significant figures out. So maybe my next mistake is an error when conversion of pm to m? Or maybe when calculating the Heisenberg Uncertainty...

I don't quite understand what you mean by unjustifiable. Sorry english isn't my strong language. But Ill try to explain what I think is wrong Most likely it is the significant figure section. The answer wants it in Ns, so I changed pm to m. (28 pm to (28E-12 m or 2.8E-11 m)) Used the Js form of...

Hello, I am a new member here. I hope I can better my physics studies here. Please take good care of me. Thank you

I know Heisenberg's Uncertainty Principle states that there has to be a minimum amount of uncertainty. Where the minimum uncertainty is hbar/2. My attempt at the solution Uncertainty in x = 28E-12 m (Turn pm into m) h=6.63E-34 (constant) hbar=1.055`19E-34 (constant) hbar/2 = 5.275986363E-35...
