Hey I'm having a few troubles with some Translations if anyone could help me out. 15. The graph of y=f(x). where f(x) = |x+4| + 1, its reflected in the y axis. This produces the same results as would translating the graph of y=f(x) to the right by how many units? I was sick for a bit...

I've spent 2 hours+ on this ridiciously easy question. I'm doing something wrong, don't you think you could help me out just a bit more then what you've been giving me? I know you know where I went wrong, and can see it just like that, but please have mercy on my brain.

1.48x10^26?

Hmm I think it has to maybe do with my MeV conversion. Its 6.25x10^-3 MeV's, I converted it to 6.25x10^3 eV. Then I converted that into J's by multiplying it by 1.6x10^-19 to get 0.735. I then multiplied that by 2 = 1.47 then divided that by 9.11x10^31 to get 1.6136x10^30. Then I took...

Yes but why is it 3 protons and 3 neutrons? How do you figure that out? I've been sick and missed some classes. Also I did it now using 3 of each, and got... 9.98x10^-27kg

Hmm okay let met think... v=(square root) 2E/m then I do Wavelength = h/mv. so I get... 4.686x10^21 as my velocity and then 1.55 x 10 ^-25 as my answer. Is that better?

Okay and for question 180... A person on a cpu game told me I should start out with 3 protons and 3 neutrons. Can you tell me why that is? I could just do the question but I want to know why. 180. If the binding energy of lithium -6 (6/3Li) nucleus is 4.9118 x 10 ^-12 J, what is the mass...

Freq of ligh= hc/E (6.63x10^-34)(3x10^8)/(6.25x10^3)(1.6x10^-19) = 1.89.x10^-10m

148. Calculate the wavelength of an electron that has kinetic energy of 6.25x10^-3 MeV. Which of these answers is right... I did two different equations cause I was unsure... 1.89x10^-10 or 6.21x10^10?

is the antineutrino just +0/0? Is that all I have to add?

145. I miss typed that it should be 6 146. umm did I just miss type again on it? it should be 3.00x10^8m/s 164.woo 165. I'm onsure about the reaction product I am missing, more help? Can you also help me out with 180?

I think I might have figured em out, anyways how about the ones I posted so far do they look right? and then... 145. r2 = r1n^2 r2/r1=n^2 1.90x10^-9/5.29x10^-11=n^2 36=n^2 n=36? Look good? 146. Is it just 3.00x18^8 m/s? Simply more of a knowledge question...

our book does little to no justice for the section, and gives a half a page of uninsightful babble.

Okay let me start off... 116. A proton travels through a magnetic field at the speed of 6.3 x 10^4 m/s perpendicular to the field. If the radius of the arc pf the deflected proton is 7.20x10^-3, what is the magnetic field strength? Thanks. 122. A proton moves through a 0.06 T magnetic...

In a particle accelerator, an alpha particle with a mass of 6.64 x10^-27 kg is moving with a speed of 2.50x10^7 m/s. It is moving perpendicularily through a magnetic field of intensity 0.150 T. Using appropriote equations and method find the radius of curvature of its path. Hope that helps
