    MHB Difference between a(t), a(v) and a(x)

    What is the difference between $a(t)$, $a(v)$ and $a(x)$? If $a(t) = \d{v}{dt}$ then what will $a(v)$ and $a(x)$ equal to? $a(t)$ is acceleration with change in time $a(v)$ is acceleration with change in velocity $a(x)$ is acceleration with change in position

    Capillary Rise in Tube: What Happens if Length is Insufficient?

    I told that's what my teacher said. If I had known the meaning I wouldn't have asked the question.

    Capillary Rise in Tube: What Happens if Length is Insufficient?

    I told that I didn't understand what the teacher told. Any link on web that explain it would be helpful. This is not a homework question.

    Capillary Rise in Tube: What Happens if Length is Insufficient?

    What happen when the capillary rise occur in a tube of insufficient length? My teacher told me that hR = constant where h is height and R is radius of sphere of which the curved surface of meniscus firm a part. She also told me that if h become less so R has to increase so radius of meniscus...

    Excess pressure on the concave side of the meniscus

    Why is there excess pressure always on the concave side or surface of the meniscus? In my book it is also written that excess pressure balance the vertical resultant forces due to surface tension. How can a pressure balance a force? My teacher said that shape of meniscus does not depend on...

    MHB Evaluating limit by factorization

    But the answer given in my book is -11. While using direct substitution I get 9. How can you get -11

    MHB Evaluating limit by factorization

    Can anyone tell me how to solve the following limit by factorization method $\lim{{x}\to{5}} \frac{x^3 + 3x^2 - 6x + 2}{ x^3 + 3x^2 - 3x - 1}$?Please tell me how to factorize such big equation?

    MHB Evaluating $\displaystyle \lim_{{x}\to{2}} f(x$): Does it Exist?

    If modulus is the absolute value then can you explain me why we use $\lim_{{x}\to{0}} \frac{x}{|x|}$ as $\lim_{{x}\to{0}} \frac{x}{-x}$ for LHL and $\lim_{{x}\to{0}} \frac{x}{x}$ for RHL for the question in which we have to show $\lim_{{x}\to{0}} \frac{x}{|x|}$ does not exist

    MHB Evaluating $\displaystyle \lim_{{x}\to{2}} f(x$): Does it Exist?

    Can you please tell me how to deal with the modulus. i know that x - |x| is the function to be used for LHL as x<2

    MHB Evaluating $\displaystyle \lim_{{x}\to{2}} f(x$): Does it Exist?

    Evaluate $\displaystyle \lim_{{x}\to{2}} f(x$) if it exist where $f(x)$ = x - |x| where x<2;4 where x = 2;3x - 5 where x>2? LHL $\displaystyle \lim_{{x}\to{2}} f(2x)$ = 4 RHL $\displaystyle \lim_{{x}\to{2}} f(3x - 5)$ = 1 Therefore the limit x tend to 2 for the function does not exist...

    MHB Left hand and right hand limit at infinity

    I finally understand now. LHL is negative infinity and RHL is positive infinity.

    MHB Left hand and right hand limit at infinity

    I already know that as the denominator becomes smaller and smaller and closer to zero the value becomes infinity. Can you tell me how to get right hand limit and left hand limit for this problem.

    MHB Left hand and right hand limit at infinity

    Show that $\lim_{{x}\to{0}}$ $\frac{1}{x}$ does not exist? Please tell me how to make LHL and RHL for this? Explain me all steps used?
