Homework Statement A 180 lb man weighs 5 lb in water. What is his percent body fat? Assume that fat has a density of 0.90 g/cc and muscle has a density of 1.06 g/cc. Water has a density of 1.0 g/cc. Although we are given the weight in lbs, it is okay to work with it like mass (as grams) or...

Homework Statement What is the specific gravity of a mixture 40% ethyl alcohol and 60% water? The specific gravity of ethyl alcohol is 0.79.Homework Equations The Attempt at a Solution He showed us a way to do it for another type of problem but I approached it a bit differently and I wanted to...

Oh thanks, so I could have stopped there and solved for T. I guess I made it too complicated. So that answers the question right?

Homework Statement "A satellite orbits the Earth in a circular orbit of radius r. If the orbital speed of the satellite is v, what is the orbital period T of the satellite in terms of v and r? You must explain how you derive the expression for the period."Homework Equations Speed =...

Thanks, that makes more sense. That sentence is just worded weirdly I guess. I'm terrible at physics anyway, give me a chemistry or organic chemistry equation and I'm all on it. lol...well thank you again, I appreciate the help!

Just a general "why" question. Why does the centripetal acceleration increase when the radius decreases? This is not a homework question but rather something I'm trying to make sense of. I read that: "The centripetal acceleration has to continuously change the velocity vector back towards the...

Find a vector with magnitude of 1.00 that bisects the angle between the vectors 5.00i + 11.0j and 2.00i - 1.00j. Give your answer in rectangular coordinates. I'm not going to lie, I am terrible at physics and I had no idea how to solve this question, so I asked someone for help. I came out...
