I am looking over my review and a few questions I am lost on: 1. The disk shaped head of a pin is 1.0mm in diameter. What is the best estimate for the number of atoms on the top layer of the pinhead. -I have no idea where to begin with this... any ideas? 2.How does density fit in when the...

Hi everyone. I need help with some organic chemistry. When I see a reaction, how do I tell whether it is SN1, SN2, E1, or E2? Also, what is it about a nucleophile that makes it good or bad? Thanks in advance.

chemistry help! hi, i really really really need help with this question, i missed 2 days of class, now i don't know what's goin on, I am completely lost, and i have a test 2morow on this topic, and a friend told me the teacher said a question of this type will be on this test. i have went...

Final Exam Question Help! HELP! I need extra help. I'm studying for my Final Exam which is tomorrow and I cannot remember how to find forces of objects on an inclined plane. The question I'm having troubles with is: A 12.5 kg crate is placed on a ramp that is at an angle of 22 degrees from...

I'm working on a small worksheet for exam review that I could get some extra credit on. I've finished the problems posted below, but would like to know if they've been done correctly. If you can help on either, please do. ------------------------------ "[3] A 6.0kg block initially at...

I have 2 problems I have forgot how to do. 1. An Arrow is shot at an angle of 45 degrees abouve the horizontal at 69 m/s. (a) How high will the arrow go? (b) what horizontal distance will the arrow travel. these are the equations I know: Dx=Vxt (Dx: verticle distance, Vx: Verticle...

Hey everybody, this here was one of the questions Cambridge university gave to students applying there these past few years, I'm having some trouble figuring out how it works, can anybody help me out? Cheers:) Consider two balls, one small and one large, the smaller ball sitting on top of the...

well doing lots of problems for finals and posting the ones i can't get...again I am havin trouble with this reflection stuff A solar sail of area A=200m^2 is at a distance 1.46e8 km from the sun. suppose the power of the sun is 10^20 kw and the sail is perfectly reflecting ( think you use...

Two blocks are connected by a string of negligible mass passing over a pulley of radius .250m and moment of inertia I. The block on the frictionless incline(it has a picture of incline with block 1 on it at theta = 37, and block 2 is hanging off the side by the pulley) is moving up with a...

On a recent exam I took, these integrals came up and I was unable to answer them correctly: \int \frac{2}{(x-1)^2+1} dx and \int \frac{2}{\sqrt{1-(x-1)^2}} dx I had absolutely no idea how to solve those 2 equations and my professor decided not to go over any of the problems...

The two questions that were on my exam, to be honest, i didnt answer because I didnt understand it enough to do so. But I am willing to learn and be shown the way to a legit answer, so please don't immediately give me answers. The questions are like this: The density of air near the...

a 3.00kg block starts from rest at the top of 30.0 degree incline and slides 2.00m down the incline in 1.50s find: a). acceleration of the block b). coefficent of kinetic friction between the block and the incline c). frictonal force acting on the block d? the speed of the block after it...

Newtons Theory & Vector Solution ---------------------------------------------------------------------- Q. Two ropes are attached to a 40kg object. The 1st rope applies a force of 25N & 2nd rope applies force of 40N. If the ropes are perpendicular to each other, what is the resultant...

I was revising for my ALevel P6 exam the other day and I came up against a very tough question... I can do parts i and ii axa = x^-1, let x = e a^2 = e a = a^-1 for part ii axa = x^-1 axax = e axax(ax)^-1 = (ax)^-1 //ax and (ax)^-1 will cancel ax = (ax)^-1 but for part iii and...

Here's the problem and I'm close to the answer, but I guess close isn't good enough on a Physics exam. A spinning solid disk, rotating with angular velocity Wo, is put down on a level surface. It slides and rolls until it reaches an angular velocity W at which it rolls without sliding. Show...

Ive got my GCSE Physics exam in a few weeks and Its going to be really hard. I need some revision techniques and tips on how to stay cool on the big day, thanks
