That last questionin in section 2 (26 and 27) (1 Viewer)

hey those last questions were confusing,how did you shift the grph and that proton thing i heard you had to drive the equation using half mv squared and then substituting it into p=mv ,that was hard i had no idea


anybody got the solution


did anyone else find it hard

 

[Captain Gh3y]

*sigh*

F = mv²/r = qvB

rearrange to mv = qBr,
ie. p = qBr.

(ii) substitute to find m

(iii) You now have m_v, rearrange the mass dilation formula and substitute to find m_o.

how did your graph look and why

 

[Husayn]

Noone asked you to sigh, if you are annoyed then don't respond.

 

[Captain Gh3y]

Shut up.

Diagonal line from where it was about 0.2 (?) photocurrent then jumped up to 8 over the domain of a few eV. 2nd line had the same x-intercept (same cutoff frequency) but sharper gradient.

 

[Vinniejaa]

well - your second graph wud have a gradient twice of that in the first one - since twice the intesity means twicet the photons as pilip von lenard discovered

in the first one u simply draw the line of best fit (even though the wordings were dodge) and the minimum energy reqd was .5 eV (i.e. answer to second question)

I think the multi-colours in captain gays signature are sending his brain into nerdy spasms.
