So i looked up Boyle's and it said PV = C P= pressure V= Volume C= constant so my question is Suppose 38 pounds of books were balanced on a syringe plunger with a cross-section area of 0.45 in^2? A) how much pressure would just the books exert on the trapped air sample...

So, for extra credit in my physics, i can submit 2 articles that are physics related and published within the previous three months with a page summary but i don't know what magazines i can find some. I don't think i can get them off the net so this is going to be hard because i don't have...

but how do you do it 1.10/1.52 =.723 sin 20=.723 then I am stuck...

snells law is n1 sin i = n2 sin r n1= 1.52 sin i = 20 deg n2 = 1.10 sin r = ? sin r actually equals 28.2 deg but i don't understand the process

so my given is 1.52 20degrees = 1.10 sin r im trying to find sin r which comes out to 18.9 degrees but I am not sure how find that, can somebody help me out please? so you do 1.10/1.52 do you divide that into sin 20?

How tall must a plane mirror be to let you see your entire reflection? I know i have to find the angle and incedince but i don't know where to go from there. i am 5 11. thanks

If the mass slides down the inclined plane fomr the top, what will the speed be when it reaches the bottom so my equation is KE=1/2mv^2 so 281 J = 1/2 (5) v^2 Im blanking out on how to cancel out the square aaah thx EDIT : I GOT IT THanks

i did.. what will "a" be if the block is 10 kg at a slope of 20 degrees

Ignoring air resistance what will the accerleration be as the block goes down the slope http://img28.exs.cx/img28/1790/Physics.jpg thanks for your time!
