1. In the middle of the page, draw two vertical lines an inch long, an inch apart, and that are parallel to each other. 2. About a half inch below the lines, draw a half-inch horizontal line that is centered between the lines. 3. Draw a line from the bottom of the left vertica...

CHEMISTRY (ionization energy)
find the ionization energy of I-, I, and I+ I know you have to use E= hc/lambda, and c=lambda x v, but how do i get v?

AP Chemistry
great thanks and for the second part i can look at the orbital diagrams' arrows right?

AP Chemistry
Which of the following electron configurations correspond to an excited state? Identify the atoms and write the ground-state electron configuration where appropriate. If the configuration is a noble gas, enter the noble gas in brackets, for example [Ne] for F -. If the configu...

I have an integration problem. INT(t+8)^2/t^4 dt

Physics
A satellite of mass m is in Keplerian orbit around a parent body of mass M >>m. The satellite has total energy E and angular momentum l, where angular momentum is measured about the parent body and the zero of potential energy is at infinity. Detnermine the semimajor axi...

Physics
A long-range jet liner flies (almost exactly) level at constant speed, subject to the forces of drag fD=(1/2)CDrhoSv^2, thrust Ft, and weight Mg. Given the plane's wing area, lift and drag coefficients, speed and takeoff mass, calculate the engine power required for level ...
