Is the tension not a result of the gravitational force?

Homework Statement Today I had a physics midterm and one question that was on it is really bugging me and my friend. We'd really appreciate it if one of the experts here could give us their spin on it (I know...bad pun ;)). The question is: A yo-yo (a solid cylinder with a string...

Thanks so much! It's actually just a small part of a larger question in a lab report but I just needed to know the theory behind the question as I was drawing a blank. The question I asked is just an example...not the actual question as I didn't want anybody to actually do the question for...

So if I have 0.75 mol of I2 then I have 1.5 mol of I? Thanks!

Hello, This question is a theory question: I have calculated the moles of molecular iodine in a problem (I2) and the next question asks to calculate the moles of atomic iodine. Do I just multiply the number I have by two (as iodine is a diatomic molecule) or is it a "trick" question and the...

Well, right after I posted it, the answer hit me so never mind. V2 = V1 + at 0m/s = V1 + (-9.81m/s2)(1.5s) V1 = 14.7 m/s [up]Thanks anyways!

Homework Statement A Soccer ball is projected at a certain angle (ϴ) above the horizon. It travels a horizontal distance of 1.2x102m in 3.0s. a) Find the horizontal velocity b) Find the initial vertical velocity (VV1). c) Find the magnitude and direction of the initial velocity...
