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.

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...

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 ...

**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?

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.
