For chem we're going over something I don't understand that well. Can anyone help? It's how electron movement makes colors of the spectrum? Thanks! ♥

The range of a projectile fired with an initial velocity (v0) at an angle x (or theta) with the horizontal is
R=(v0sin2(x))/g, where g is acceleration due to gravity. find the angle x such that the range is a minimum.
Ok, well i took the derivative of it, (v0 and g are constants, so it would just be like taking the derivative of sin2x.
but then, im stuck.
i set it to zero, right, and then find those values.
but what i got for a derivative doesnt match that in the back of the book.
what is the correct derivative of this function?

Is is a powerpoint presentation about space and it compares the Earth with the Inner Planets then it compares all the planets, then it compares alll the planets to the sun, then it compares the solar system to the galaxy then to the known universe. Where can I get it?

The escape velocity of a bullet from the surface of planet Y is 1759.0 m/s. Calculate the escape velocity from the surface of the planet X if the mass of planet X is 1.53 times that of Y, and its radius is 0.807 times the radius of Y.

On planet Zog, Mr. Spock measures that it takes 1.44 s for a mass of 0.3 kg to hit the ground when released from rest from a height of 2.73 m. Calculate the size of the acceleration of gravity on that planet.

He decides to repeat the experiment. Calculate the work he must do to move the mass from the ground back up to its initial height.

This is for research for my novel. I've asked some laser lights questions awhile back on how they worked and if they give shock. How do you reflect laser light or turn them off at a cave, which is boobytrapped by them, when there's no deactivation/activation device in sight? Spray from aerosol can? Rocks thrown at center of laser lights? Reflection from mirror, without breaking the lights, not starting fire or causing a cave-in? Are they other ways? I'm interested to know. I believe there's a similar question asked before.

I am to have the lap band surgery on Nov. 27th. I just started Biaxin 500mg. BID today, Nov. 16th for 7 days. I will be finished on the 24th, 3 days before the surgery. I accidentally scratched myself and it got infected. Will this keep me from having surgery? and will the Biaxin I took interfere in any way with the anethesia?
