Can you please suggest some good books a learning Java and electronics? I have learned C++ and I plan to learn Java now. I also want to begin learning electronics by myself. Thank you Elixer

So the ball has an angular momentum as well. But , consider the following The ball on the circular track has an angular velocity w = squareroot(g/R)[where R = radius of circular path ,g = acceleration due to Earth's gravity] So, as the radius of the path the ball travels decreases, w...

I watched MIT OCW PHYSICS 8.01 lectures, and in lecture no.13, i saw a puzzling demonstration. Link :http://ocw.mit.edu/OcwWeb/Physics/8-01Physics-IFall1999/VideoLectures/detail/embed13.htm" I don't understand, what can be the reason for the oscillations of ball on the track with the...

Thank you so much! That points out the importance of signs and vector diagrams. Yes, so the equations are: CASE 1: angle = 18o -2.3 = -6.18t -4.9t2 t = 0.3s ux = ucos(18o) = 19.02m/s so, s1 = 19.02 * 0.3 = 5.706 m CASE 2: angle = 8o -2.3 = -2.78t - 4.9t2 t = 0.46s ux = ucos(8o)...

Homework Statement In a jump spike, a volleyball player slams the ball from overhead and toward the opposite floor. Controlling the angle of the spike is difficult.Suppose a ball is spiked from a height of 2.30 m with an initial speed of 20.0 m/s at a downward angle of 18.00o. How much farther...

Hello! I am writing the AP CALCULUS BC test on 5 May, 2010.All the best to all people who are writing their AP tests. Does anybody have any tips/ suggestions for revision or some ideas about really important/expected topics? Thank you. Elixer

Hi! (I hope I am posting in the right forum.) I want to learn mechanical drawing using AUTOCAD. But I can't purchase the software. Can someone , please, please suggest an open source / free alternative ? I know I will use AUTOCAD in college , I want some practice in drawing and an idea...

You can download this software - http://www.filehippo.com/download_pdfcreator/" It is legally free and useful.

So, (4,0) lies on the graph of f-1(x), y = f-1(x) dy / dx = 1/(4y + 20e(5y)) Hence , slope of f-1(x) , dy / dx = 1/20 which implies , slope of the normal to the graph = -1 /(1/20) = -20 Ans = -20 Am I correct? Thanks a lot!

Homework Statement f(x) = 2x2 + 4e(5x) is invertible. Give the slope of the normal line to the graph of f-1 at x = 4. Homework Equations (Given in question) The Attempt at a Solution I don't know how to solve this question. But , I found the following:- f(4) = 32 + 4e20 let y...

Can somebody please reply? Thank you.

Is it advisable to solve problems from Irodov and Resnick , Halliday , Walker for AP PHYSICS C :MECHANICS AND ELECTRICITY & MAGNETISM ? I am self-studying, so any website links to practice problems(except Collegeboard) will be really helpful, please. Thank you.
