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.
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.
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?
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?
