Kfinal + Ugravfinal = Kinitial + Ugravinitial which i ended up with Vfinal^2 + [2GM/r] = Vinitial^2 + [2GM/r] I believe I need to solve for r but this is where I got stuck.

A satellite in an elliptical orbit has a speed of 9.00km/s when it is at its closes approach to the Earth(perigee). The satellite is 7.00x10^6 m from the center of the Earth at this time. When the satellite is at its greatest distance from the center of the Earth (apogee), its...

i just wanted another opinion

chemistry
give a definition of ionic bonding

Chemistry
Put in order from strongest to weakest: London Dispersion Forces, Hydrogen Bonds, Dipole-dipole interactions, ionic bonding, and covalent bonding.

chemistry
what are indicators of strong intermolecular forces?

math
the way i would work it is first move the equation to standard form because i find it easier to work it that way. 2x-3y=-5 -3y=-2x-5 y=2/3x+5/3 an equation perpendicular to this equation would have a slope of -3/2 because perpendicular lines have opposite recirocal slopes. now...

math
first use y2-y1/x2-x1 to find the slope -4-3/2-(-1)=-7/3 then(assuming the equation is parellel)use point slope form y-y=slope(x-x) y-3=-7/3(x-(-1)) y-3=-7/3x-7/3 y=-7/3x+2/3 then to put it in standard form it must be in the Ax+By=C form with no fractions and the leading ...

chemistry
what if the question doesnt say that the temperature and pressure stay constant. for example..3.0L of a gas has a pressure of 12.0 atm. What is the new pressure if the gas is expanded to 17.0L?....would you assume that the temperature would stay the same or is there another ...

chemistry
5.0 moles of a gas is put into a container of 2.0L. More gas is added to the flask s othat there is now 15 moles of the gas present. What must the new volume be if temperature and pressure are to remain constant?

chemistry
is the other element mercury?

chemistry
at STP, chlorine is a gas but bromine is a liquid. why is this?

chemistry
so when you look up the electronegativity values, the lower value is the positive end and the higher value is the negative end?

chemistry
what type of intermolecular bonding would be expected between molecules of carbon monoxide and why?

chemistry
sorry this question is out of a lab and i didn't think that nobody would understand the change in temperature since they havent done the lab but that does answer my question.

chemistry
n-pentane and 1-butanol have nearly the same molecular weights but significantly different change in temperature values. explain the difference in change in temperature values of these substances based on their intermolecular forces.
