APPRECIATIVE STUDENT

Thank you for your help :) "The piecewise function f(x)= n(x^3)-x______when____x<(or=to)1 =m(x^2)+5_______when_____x>(or=to)1 is differentiable everywhere. What is n? If you could explain step by step how to do this that would be great because I just do n...

Thank you for your help. I don't know how to do this, so if you could explain step by step how to do this, that would be really good.... "A rough approximation for ln(5) is 1.609. Use this apporximation and differentials to approximate ln(521/100) thanks

thank you for your help! my question is :how do you find the magnitude of the electric field that will balance the weight of an electron?

hi -- thank you for your help before-- that makes sense-- also, im stuck on this: if there is a negative2.5 microcoulomb charge 1 m away from a 6microcoulomb charge, then at what point (other than infinity) is the electric field = zero? Sorry, i have no i...

thank you!
