aha....# of prot and electrons =35 same as atomic number. #of neutons=mass number - atomic number=44 neutrons... so 35 protons,44 neutrons and 35 electrons .....hows that???

so 2 X4 ^2 = 32 so 32 is correct ....... thanks andy

alright thank you, ill post a question later on when i develop a thesis

No, incorrect. Be carefull with this, your: 18MB x 10^6 x 8 bits = 144,000,00 Should in fact be: 18mb x 2^20 x 8 bits = 150,994,994 Your second part is correct, so its 4 megabits per second = 4 x 10^6 = 4,000,000 Answer: 150994994 / 4000000 = 37.75 second...

The two statements above is wrong. you first move around the dy/dx = (y-1)/x^2 into dy/(y-1) = dx/x^2 Then you integral where it turns to ln( (y-1)/C ) = -1/x Next you move the e from the ln to the other side (y-1)/C = e^(-1/x) After that you times C to b...

when dealing with linear functions, the general formula is y= mx + c..where m is the gradient and c is the y-intercept. To find the value of x simply make y = to zero.hence the equation(y=1/2-7) is a linear function because if substituted in the general f...
