Homework Statement The parabola y=1/2 x^2 divides the disk x^2+y^2 <or= to 8 into two equal parts. Find the area of both parts. Homework Equations The Attempt at a Solution I have no idea of how to go about solving this. We haven't done any application problems until now and when...

Homework Statement Two carts of equal mass (15 Kg) have a head on elastic collision. The first cart has a velocity of 18.5 m/s to the right, and the second has a velocity of 12 m/s to the left. What are the velocities of the two carts after the collision? Homework Equations Since it is...

Homework Statement The problem states to find the maximum acceleration and velocity, the accleration and velocity when the displacement (x) is 1.00cm, and the equation of motion as a function of time if the displacement is A (amplitude) at t=0. We're given that the period (T) is 0.500s and...

Homework Statement So the problem states that we have a (+) enantiomer of a coumpund with an optical rotation of 50*. If a pure sample containes 42% of the (+) enantiomer and 58% of the (-) enantioimer, what is the optical rotation value. (By * i mean degrees) Homework Equations I'm not...

Homework Statement I have to rearange both equations to find mass, radius, and velocity (each of them seperately). Homework Equations I know that Centripetal Force= mass x (velocty^2/radius). In this case velocity is also equal to 2∏r/T (where T is the period), so I subsituted that in for...

Homework Statement What is the minimum work needed to push a 950-kg car 810m up along a 9.0 degree incline? (a) Ignore friction. (b) Assume the effective coefficient of friction working against the car is 0.25. Homework Equations I know that W=F x displacement x cos. In the second part of...

Homework Statement Find dy/dx when y=\sqrt{ln x} Homework Equations d/dx of ln x is equal to 1/x times d/dx of x. The Attempt at a Solution I tried to raise the ln x to the 1/2 power instead of keeping it under a square root sign, but I had no luck. I'm struggling with Calculus. I...

I was wondering as to just how deeply chemistry relies on calculus. I'm great at all my chemistry homework and studies, but calculus is a real struggle for me. Not that it's impossible, just with the resources I have it's incredibly difficult. I worry that in the future, as in when I get to grad...

Ok, thank you. I appreciate the help in figuring it out. I am a Chemistry major, Junior year in college. Only thing I've done with magnetism is a brief explanation of dipole moments and the different kinds of said moments, along with electron spin and polar molecules sooooo I don't know much...

So I was goofing off yesterday trying to shoot a magnet off of another magnet because of their similar forces and starting playing with a paperclip. I noticed if I put the paper clip to one magnet, it stuck, as it should. However, when I put the other magnet on the other side of the paper clip...

This is my first course in Calculus as a Junior in college and it's already much different then what I'm used to. I could use some help in understanding several theorems used to describe limits. The first states that the lim k = k as x--> aThe book describes it as being a constant function...

So my friend came home from work and asked me why adding vinegar to water aids in evaporatoin. He said they had them clean with this solution because it helped the water dry up faster. However, I've only had two years of study in chemistry and I can't say I know for certain. I know that...

Can someone help me understand the concept of chemcial equilbrium. I think I understand in a certain chemical reaction, know matter the amount of reactants or products, the equilibrium constant will remain approximatly the same. I don't fully understand how the equation to solve for the...

Ok, so I watched a horror movie recently and they did the whole drop a rock down a cavern and see how long it took to hit the bottom. Couldn't you find the approximate distance through this? Not just a guess like "Oh that took a little bit so it's waaaay down there". If two objects...

Ok, so this may be more of a chemistry oriented question, but physics is pretty much the foundation of chemistry. We've covered thermochemistry to some extent in my Properties of General Chem class, and I had a thought. Since heat is associated with the random motion of atoms and molecules...
