    Estimating the Size of a 1-Ton Rock: Relating Density and Volume

    I'm unfamiliar with what edge size is and how to find it; I'm just beginning taking Physics this semester. It talks about estimating the diameter of a 1-ton rock, but is doing so no longer necessary due to already having the volume, or am I overlooking something? You don't think answering...

    Estimating the Size of a 1-Ton Rock: Relating Density and Volume

    Homework Statement How big is a ton? That is, what is the volume of something that weighs a ton? To be specific, estimate the diameter of a 1-ton rock, but first make a wild guess: will it be 1ft across, 3ft, or the size of a car? [Hint: Rock has mass per volume about 3 times that of water...

    Required Precision for GPS Distance Measurement

    So, 8? Thanks for your help. I figured this would be overlooked since it looks like cake compared to the other questions I've seen asked here.

    Required Precision for GPS Distance Measurement

    So that makes the percent accuracy 1 x 10^5 % (or 0.00001%)? What about significant figures in the distance? I don't understand what the question means by that... (This is from a worksheet I have.)

    Required Precision for GPS Distance Measurement

    Homework Statement GPS can be used to determine positions with great accuracy. The system works by determining the distance between the observer and each of the several satellites orbiting Earth. If one of the satellites is at a distance of 20,000 km from you, what percent accuracy in the...
