I need help with the second part too... anyone???
I live in the middle of no where. It takes a 45 minutes to get to a local store and the closet libray is 1 hour and 15 minute drive from my house. And my parents won't let me buy things online.
There is one big problem I don't have the book my school didn't give me one. So how the heck am I suppose to do this problem when I don't have the book.
no other criteria was given
I managed to get it :) though for others who might be looking to solve this for their practice questions Convert Kb to Ka Ka = kw/Kb then just use an ice table with Ka=x^2/ 0.300M-x (x is small) and just -log[H3O+)
Ok... but I still don't get it... Is there a formula type thing that could help me?
But what about the second angle? There is another one besides theta that I don't know what to do about - but that explanation just helped alot with all the other problems!
Compute the net force along the direction of the plane, making sure to subtract friction (if any) and the component of weight along the plane (W sin A). -That is the part that I don't get how to do...
