    How do I interpret and graph Newton's second law data?

    Homework Statement Hi, I am doing this lab this week, but before I do it I have a few questions. ( it has to be completed in class so I want to be prepared). First, these are the three pages of the lab questions...

    Making a graph of CuSO4 concentration vs volume of solution

    Thank you. Sorry if I was being a little vague but you answered exactly what I kept worrying about. What I shouldve said in my original post was 1) if my work is correct and 2) what to put on the x-axis and y axis

    Making a graph of CuSO4 concentration vs volume of solution

    Homework Statement Hi, I don't even know where to begin with this type of graph. It does say that the graph should be a straight line. This is for one of my questions for my lab that I am completing. This is the link of mytable with info...

    What is the difference between apparent weight and true weight in elevators?

    So for my question 2 , it would be upwards and downwards?

    What is the difference between apparent weight and true weight in elevators?

    Homework Statement Hi everyone,I just want to know if my answers are correct. Homework EquationsThe Attempt at a Solution 1. For each situation, indicate whether the normal force exerted on you will be gater tha,less than or equal to your true weight. a) Elevator starts to move down from the...

    Limit at infinity with radicals

    LOL. To be honest I just didnt feel like typing but now that you made me realize someone else might need the help , might as well. Ok well the way I figured out the answer is probably not the way everyone else does. Work: 1) I factored out x^(1/5) . After the factoring I am left with x^(1/5)...

    Limit at infinity with radicals

    Sorry everyone! I forgot I asked this question. I figured it out now.

    Arctan limit (without L'Hopital's Rule)

    Okay I just noticed I actually put two brackets. I can see now why everyone is confused and guessing. Thanks for correction.

    Arctan limit (without L'Hopital's Rule)

    Its the second one , but in my original post that's exactly how I entered it.

    Arctan limit (without L'Hopital's Rule)

    The answer is not in the book. My book has a weird way of giving the answers. Only gives for odd numbered questions and this ones an even so I have no way of knowing if my answer is right. So instead of -45 it would be -pi/4 ?

    Arctan limit (without L'Hopital's Rule)

    Homework Statement Limx-->positive infty arctan(1+x)/(1-x) Homework EquationsThe Attempt at a Solution I just need to know if my answer is right. Knowing that when the leading coefficients of the x when its the same, then the answer is just the ratio. So it would be -1. Then in my calculator...

    Limits...what am I doing wrong ? (Without hopital)

    Homework Statement Limx--->positive infinity sqrt(3x^5-2x) - sqrt(3x^5-7x) Homework EquationsThe Attempt at a Solution The first thing I did was rationalize. I got (5x)/ [ sqrt(3x^5-2x) + sqrt(3x^5-7x)]. Then I divided the top and bottom by x^5 but this is where I feel like I am doing...

    Inifinity limit with natural log

    Yes that's what I did. So my final answer then should be Ln(1/2) ?

    Inifinity limit with natural log

    Homework Statement Limx--> ∞ Ln(x^2-1) -Ln(2x^2+3) Homework EquationsThe Attempt at a Solution Ln(x^2-1)/(2x^2+3) Then I divided the top and bottom by x^2 so in the end I got (1/2). Is this right?

    Limit at infinity with radicals

    Homework Statement lim as x tends to -∞ (x)^3/5 - (x)^1/5 Homework EquationsThe Attempt at a Solution The first thing I did was convert it into a radical so it becomes fifthroot√x^3 - fifthroot√x. Then I rationalized to get ( x^3-x)/(fifthrt√x^3+fifthroot√x) . I then divided the top by x^3...
