At 25 °C, the density of a 50 % (by mass) ethanol/water solution is 0.914 g/cc. Given that the partial molar volume of water in the solution is 17.4 cc/mol, what is the partial molar volume of the ethanol?

never mind, i figured it out

A centrifuge rotor has a moment of inertia of 3.30 10-2 kg·m2. How much energy is required to bring it from rest to 10000 rpm? I used KE=1/2Iw^2, but that answer i'm getting is incorrect. what am i missing?

This question didn't post properly. I was able to find the acceleration (1.79m/s^2), having difficulties getting the force. what would "h" be in your equation? to me that symbolizes height and there's no height in this problem.

Two crates, of mass m1 = 60 kg and m2 = 130 kg, are in contact and at rest on a horizontal surface (Fig. 4-54). A 620 N force is exerted on the 60 kg crate. The coefficient of kinetic friction is 0.15 a)Calculate the acceleration of the system. b) calculate the force that each...

That's odd, you can't solve this problem if it is not set to equal something. The only thing i can think of is to set it equal to 0 ans solve for j.

what is this supposed to be equal to? You cannot combine -108 and -9j since they are not like terms (they don't both have j).

What is true of a square root? You cannot take the square root of a negative number (if you're dealing with real numbers anyway). So for what value of X would 12x-24 be 0? anything below that number would make 12x-24 negative and therefore not in the domain.
