Thread: Got a physics question or interested in physics?

I have an account in it its cool. i mean AWSOM.

I have an account but I can't permanently log in. And I know that I'm using the correct password because it does momentarily log me in and shows the message "Thank you for logging in, Mr Rayon". However, it then sends me to a page where I am not logged in.

hey since you guys have a sister and brother site called chem and physics. Is it possible for you to link my account to your siblings so I can save time registering.

I'm already on it as well Another great helper

Btw are those two websites also run by the owner/webmaster of this website?

I dont like Physics so much. but after reading your article i think that physics is so intresting.
Its true that in our world with out physice nothing ts possible..

what about physics-related maths problems?

especially those that involve calculus.

I get "Site cannot be found" now.

A book, which may be modelled as a particle of weight 8N rests in equilibrium on a desk top inclined at 28 degree to the horizontal. ind the frictional force acting on the book. he coefficients of friction between the book and the desk top is 0.6. Determine whether the equilibrium is limiting.

F= 8 sin 28x.6= 3.75 ( parallel)
R= 8 cos(28)= 4.5

Answer given is 3.76N and friction is not limiting. may I know why friction is not limiting? Please explain

do not piggy-back new questions on an old thread ... next time, start a new physics thread in the Math Topics forum.

Sorry and thanks for explainng

It's too late for this comment for most users but the Physics and Chem sites are down until the owner comes back and resuscitates them. I don't recall if we have a Biology forum or if it was in the planning stages. But if we did that's down too. we're focusing on the Math site at the moment.
