  1. This is absolutely ridiculous.

     

    I defy ANY parent to tell their child that they cannot go to the library.

     

    And for some reason, it broke my heart to use the above grammar.

     

    Does your church have a youth group that you could join?

  2. I suggested ampicillin since it is well studied in the lab, for both resistance and non-resistance. You can buy both resistant and non-resistant versions of the same bacterium. You can also induce resistance with plasmids (rings of DNA) that can also be bought.

     

    As for feasibility, I really can't comment on that :)

     

    I can tell you that it would make a DAMN interesting science fair project if you could pull it off.

  3. I like the "go to the library" idea by Mr Skeptic. Perhaps a study group. With people some friends from Sunday school. Then a friend from Sunday school. Then a girl from Sunday school. etc etc.

     

    I'm half joking ^^^

     

    But a safe place (like a library) to hang out with a few friends is very difficult (one could argue that it is abusive) to reject.

  4. You should see what it's like at our campus. It's a bit better, now that the voter registration deadline is past.

     

    It's like every 30 feet there is someone with a clipboard asking questions about the candidates.

  5. What exactly do you do in your free time? I think you mentioned lying around on your bed with an iPod...but seriously?

     

    Get outta the house more!

     

    I can almost guarantee you that if a girl asks about what you do for fun, and all you can come up with is the above...

     

    There are other nice benefits too. Like getting to meet people. And having fun.

     

    A part of me finds it funny that you came here for help :D

  6. If you and your girl get webcams, you can video conference with each other over the internet.

     

    I hate to impose my views on your family, but have you actually tried talking with your parents about it? They may be more accepting than you are giving them credit for.

  7. Looks like iNow is passing out heart attacks :D

     

    Anyhow, I think the local ice cream company (Graeter's, if anyone is familiar) uses some gelatin mixed in with the starting ingredients to help the ice cream stay...soft-serve-esque, for lack of a better term.

     

    Nestle makes a bunch of different types of chocolate chips (intended for chocolate chip cookies) that you could try.

  8. A full shell of electrons is more stable (i.e. lower energy) than an unfilled shell. Atoms bond to each other to fill their outer shell of electrons (all the inner ones are already full) so an atom that already has a full outer shell won't really bond to anything else.

  9. You can take a cup or so, and dump it in a garbage disposal (the grinder thing in a sink). Turn on the hot water, and then turn on the garbage disposal. It creates a kind of volcano like plume. You'll have to tweak the dry ice amount based on the size of your garbage disposal.

     

    Dry ice in some rubbing alcohol will make the alcohol kind of viscous, IIRC. Looks kind of neat, but is also sorta boring.

  10. This seems slightly draconian.

     

    Perhaps a tax on incandescent light bulbs, where all proceeds from the tax go to funding environmental efforts would be better placed? Something along the lines of what governments do with cigarettes, so that if a person wanted to use an incandescent bulb, they could choose to pay extra for the luxury (that extra being used to clean up the mess associated with the aforementioned bulb).

  11. Use the same method you used to calculate the force parallel.

     

    F(perp) = F(g)*cos(24.23)

     

    The F(perp) is your normal force. You calculate the kinetic friction the same way you calculate the static friction.

     

    F(f) = F(perp)*u(kinetic)

     

    This force "takes away" from the force accelerating the box, so you subtract it from the force accelerating the box. In physics terms, this force is acting in an opposite direction from the force parallel.

     

    So subtract the kinetic friction force from the force parallel. The number that this gives you is the net force on the box. The net force, divided by the mass, will give you the acceleration.

  12. sin(70) = F(x)/F(a), or F(a)*sin(70) = F(x)

     

    Remember that sine is opposite over hypotenuse.

     

    Replace your .94 with F(a)*sin(70), and you will get:

     

    F(y) = F(a)*sin(70)*.253 + .8*9.8

     

    Now you have an equation with two variables, and you need it to be in one variable. BTW, the 9.8 comes from converting kg to newtons, as the kg is not a unit of weight, it is a unit of mass.

     

    So you need to find a relation between F(y) and F(a):

     

    cos(70) = F(y)/F(a), or F(a)*cos(70) = F(y)

     

    Substitute this in for F(y), and you will have an equation in one variable, which can then be solved using algebra.

     

    While you can do this problem using sine and cosine, on a test you may want to try the tangent function, as it can often get you to your answer in a more straightforward route. If you decide to do that, make sure you practice it.
