Bonsoir bonsoir,

I have just finished writing my rationale. I'm not sure if it's okay to post this on a public forum, as plagiarism detectors, but I would like to get it checked by you smort people! Any ideas on what to do? Tyyy

    No one would be able to access that, except you guys right? Because I don't want anyone stealing my work 😅

    Ohhh, but it says to share the link means to let everyone anywhere have access T.T

    Bonsoir bonsoir,

    Anyway ignoring that for now, and hopefully finding a way to share it privately, but I don't know how to do the uncertainty for 1/sqrt sin theta. It's just against time. I've found the times uncertainty, but I don't understand how to do it for the angle one 1/sqrt sin theta:

      Hey lucy_,

      Yeah, I think you would need our email addresses to share it privately but it seems there's no way of giving my email to your privately either. So, maybe you could make a google drive link, post it really quickly and I can download it and then you can delete/remove the link?

      As for your uncertainty question, you do not need to "find" / "calculate" the uncertainty of the independent variable. Since you are not measuring it, there is no uncertainty in its calculations/measurements. There is only uncertainty in the equipment in which you measure the angles (e.g. a protractor). To find that, it's just the smallest increment on the tool which it seems you have already figured out (in the brackets next to the heading Angle). This would apply to the 1/sqrt sin theta as these are not dependent variable values if that makes sense. That 1/sqrt sin theta will stay constant whether or not you do the experiment 1 time or 100 times.

      I hope that makes sense.

      Okay cool, I'll let you know about the rationale when I've done it, cause I actually need to redo it completely. I didn't understand the oe, so I didn't really know what to talk about, but hopefully by Sunday or so I can send it through.

      Also with the uncertainties, my teacher said that I need to propagate the uncertainty to find 1/sqrt sin theta, and I wasn't sure what she meant. But if so, then the uncertainty for both the actual angles and 1/sqrt sin theta would be +-0.5 degrees (for like every measurement?).

      Thanks by the way, you both are very helpful!

      Hello everyone,

      I was wondering if you guys could help me with this physics question?
      A water skier at the Moomba Masters competition in Melbourne leaves a ramp at a speed of 50 km h−1 and at an angle of 30°. The edge of the ramp is 1.7 m above the water. Calculate:

      a) the range of the jump

      b) the velocity at which the jumper hits the water.

      Thank you!!!
