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...

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...

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 ...

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 ...

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?

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

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.
