Question is: A plastic slab has a thickness of h and a density p_s . when a swimmer of mass m is resting on it, the slab floats in fresh water with its top at the same level as the water surface. find the area of the slab. give your answer in terms of density of water p_w , p_s , h and m so...

yeah it makes sense, I am just having a hard time visualizing a freebody diagram with tension...need more practice i guess. my prof this year seems to rush her answers and doesn't provide much help 8/ so thanks for the help.

so then T is just m2g? that makes sense i guess. I am having trouble actually understanding the concept of tension in general, if anyone has any suggested websites i can read that would help me out that would be great too. thanks for the help.

alright the question asks An air puck of mass m1 is tied to a string and allowed to revolve in a circle of radius R on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and a counterweight of mass m2 is tied to it (see the figure...

Alright that makes sense. So can it be said that the location of the C=C bond results in 1-butene creating two products and 2-butene only creating one? What you said makes perfect sense. I'm just trying to figure out a way of applying it within the scope of the lesson material.

2-butene CH3CH=CHCH3 + HCl -> CH3CH2-CHCH3+Cl 1-butene CH2=CHCH2CH3 +HCl -> CH3-CHCH2CH3+Cl is that correct?

I thought it might be, but I don't think the number of isomers has anything to do with the number of products 2-butene creates when it is combined with hydrogen chlroide. Plus it is already stated that 2-butene only forms one product (2-chlorobutane) when it is combined with hydrogen chloride...

Yeah I'm pretty much stumped on this one... Basically I'm supposed to explain the following: When 2-butene reacts with hydrogen chloride gas, only one product is detected, whereas when 1-butene reacts similarly two products are usually found. My best guess is the difference in position...

for a) although the water molecules are aligning themselves with the ehtanol molecules isn't the whole point of a miscable substance based on the fact that the randomness of the system increases allowing the two substances to become completely miscible with one another? for b) since the...

Considering the following equilibrium reaction A(g) \longleftrightarrow 2B(g) + C(g) And the question: When 1.00 mol of A is placed in a 4.00 L container at temperature t, the concentration of C at equilibrium is 0.050 mol/L. What is the equilibrium constant for the reaction at...

http://michael_walker.shackspace.com/question.jpg I've included the exact excerpt from my workbook. From that we can see that the paint thinner is made up of methyl benzene (C6H5CH2) (toluene), is non-polar and is an example of van der Waals bonding. The vegetable oil contains oleic...

In an experiment related to bonding in liquid I was required to stir three liquids: Water, Paint Thinner, and Vegetable oil. Thereby creating a vortex in each liquid and recording the depth of the vortex plus the time the vortex took to disappear. My results where that water produced the deepest...

wow man thanks for the help here... this question was getting to me one of those questions i guess when you finally get the answer its like "What the hell i should have known that!"

Only problem is I believe that stating the exact atomic radius is beyond the scope of the question and this part (if not all) of the course. I also believe that just simply stating their atomic radius does not explain fully why S2- is located where it is.

Okay I think this question has been addressed slightly before however I seem to be having difficulty on it still. The question asks: Arrange the following atoms or ions in order of increasing radius Cl, S2-, K, K+, O Now I have them arranged as O < Cl < K+ < S2- < K The arrangement...
