    Problem with Differentiation Using Quotient Rule

    I am attempting to find the second derivative of a function: h(x) = [(x^2)-1] / [2x-(x^2)] I proceeded by using the Quotient Rule, and I found the following as the first derivative. (It is correct.) h`(x) = [2(x^2)-2x+2] / [2x-(x^2)]^2 Next, I tried using the Quotient Rule again, and...

    Why does Benedict's test require heat for accurate results?

    Hello, I just have a quick question about Benedict's test... Why must the substance be boiled in order to get the results (change of color based on the percent of reducing sugar)? This is really bothering me! Please help if you can! Thanks in advance! PS

    Is My Calculated Gravity in Diluted Gravity Lab Unusual?

    Is g in this formula supposed to be equal to a value less than 9.81? I would think so because this gravity is being diluted by the ramp's presence. (i.e. it is not in free fall). So I would think that g represents the amount of acceleration due to gravity that is still present despite the...

    Is My Calculated Gravity in Diluted Gravity Lab Unusual?

    Perhaps, my teammate holding the stopwatch had mistaken the 13.xx s for what he thought was 3.xx s I have replaced them to 13 for experimental sake and the results make more sense. Anyways, this lab won't be worth much, at least it's the data and not my calculations! Thanks a lot for the help! =D

    Assignment about Galileo and his contributions to science

    As far as I know, inductive reasoning is to formulate new ideas and theories rather than using what you already know and has been discovered by others (=deductive). Heliocentric is Galileo's theory of the sun being the center (of the solar system), rather than it being the Earth (=geocentric)...

    Anyone have an idea? This is due soon and I want to have it right! =D Thanks

    Is My Calculated Gravity in Diluted Gravity Lab Unusual?

    Hi, thanks for the replies! I indeed repeated the lab three times in order to achieve more accurate results. So I suppose that would lead to the problem being in my calculations. My times were: 3.08 s, 3.32 s and 3.33 s (average of 3.24) The height of the ramp's heightened edge was...

    Is My Calculated Gravity in Diluted Gravity Lab Unusual?

    Hey, I'm new here but I have a physics question with my homework! hehe We're working with dilution in gravity and we did a lab where we were to roll a marble down a ramp and record such variables as time and distance in order to afterwards calculate the acceleration and gravity force...
