A moderate wind accelerates a pebble over a horizontal xy plane with a constant acceleration a = (5.00 m/s^2)i + (7.00 m/s^2)j. At time t = 0, the velocity is (4.00 m/s)i. What are the (a) magnitude and (b) angle of its velocity when it has been displaced by 12.0 m. parallel to the x axis?

So, I am having an argument with someone about whether a leather couch or at least the leather part of the leather couch is or is not water proof. I dont own one so I am asking people who do. If you spill a drink on your leather couch, the liquid will just bead and you can wipe it up correct? Does it stain the couch at all? What do you think?

:N(3bonds)C(1bond)O:::(-) <------> ?
(: means 1 long pair, ::: means 3 long pairs, (-) negative charge, and there are two errous one from 3 bonds going to N, the othere one from O going to C, errous shows electron pair movements

A) ::N(-)=C=O::
B) ::N(-)=C-O::
C)::N(-)(3bonds)C=O::
D)::N(-)=C=O:::

I was thinking it is A, but my friend says it is B. We to find who is right.

My sister's science teacher showed them this experiment. First the teacher put a certain amout of water that went in to this tube and into a box (not a cardbord) that didn't have any electronic device, it was just a regular box. Then it went out of the box (from the tube) and was put back into the jar. When they looked at it, it had more water than before!! Her teacher said that she won't tell them until they become a science teacher (and I know my sister is not going to become one!)! My siste and I are dying to know the secret! Can anyone tell me??

a day ago I asked about the T flip flop but no one gave me a circuit figure, here is what I am trying to do , I have a led that i want it to be dim when the switch is open , when I close the switch it will glow, when opening the switch again I want it ti still glow , the next time I close the switch I want it to dim (go off) , I tried that with a simulation program but not working , here it is , I putted the JK flip flop and connected the J and K with one switch , and I fed the CK pin with a pulser, and in the output i putted one LED for the Q , but here it is what goes when I open the switch the LED will flash very quickly , when i close the switch then , It will randomly select any of dimming or glowing , I don't want that ,, please attach or link me to an application so I can figure out how it works, Thanks...
