Could you kindly explain how? When I plug the values in my calculator I get 64.27.

Thanks for your suggestion!

sorry just seeing your message now. Actually the question asked to show the expression of uncertainty. I asked the TA and this is apparently correct based on the method in the attached image.

Hi guys can someone look at my work for uncertainty and let me know if it makes sense.

aha thank you for clarifying this. It makes sense.

well I think the displacement should be 530-360 = 170. But in a group chat some students are adamant that the displacement is simply the angle given - which in this case would be 530 degrees.

Why would someone think the displacement is equal to the given angle. It doesn't make any sense.

Thanks guys! very helpful.

ah that makes sense. I always over complicate things. Thank you for your feedback. Also, if I wanted to know the displacement of the inexperienced driver in the roundabout, would it simply be 530 - 2*360?

Can someone look at my solution to see if it is correct.

Ok Thank You!

Hi Guys I've attempted the question but not sure if the approach I used is correct. Would someone please have a look at my solution and let me know if it makes sense. Thanks!

I don't understand why CH3CH2C(CH3)2CH(CH2CH3)CH3 is 2 ethyl-3,3 dimethyl - pentane and not 3-methyl-4,4-dimethylhexane. When I expand the condensed formula above and count the longest carbon chain, it seem it is a hexane rather than pentane. Can someone please clarify? Homework Statement Write...

So it should be CH3CH(CH2CH3)CH2CH3?
