    Finding the Uncertainty in the motion of a pendulum

    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.

    Angular Distance driven by a car going around a roundabout

    aha thank you for clarifying this. It makes sense.

    Angular Distance driven by a car going around a roundabout

    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.

    Angular Distance driven by a car going around a roundabout

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

    Angular Distance driven by a car going around a roundabout

    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?

    IUPAC NAME for CH3CH2C(CH3)2CH(CH2CH3)CH3

    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...
