Homework Statement What multiple of the distance between the centre of the Earth and that of the moon is the distance between the centre of the Earth and a geostationary satellite which above a fixed location on the equator?Take the cycle of revolution to the moon around the Earth to be 27...

Yes I am using ideal gas law,..my mistake. I got it thanks

Damn it I had never felt so foolish,..thanks I got it

It gives me this: 12+\sqrt{36-a}=14 could I be going wrong somewhere?

What do you mean?I square both sides?

I think that the PV graph in this case should be a straight line parallel to the x-axis since the pressure is constant but the volume is varying(since the piston is moving). I am not sure about this but since the pressure is constant I think this is an isobaric process and the work done can be...

Homework Statement Get the value of a if \sqrt{6-\sqrt{a}}+\sqrt{6+\sqrt{a}}=\sqrt{14} The Attempt at a Solution nothing succesfull Feel free to move this thread,..I actually place it here to tap more brains

I think they are equal since every single charge induces an opposite charge on the conductor. The opposite charges on the conductor that correspond to those on the inducing material are assumed to be all earthed.

I have edited the question. It is not stated that the gas is monoatomic and that is one of the things that make me think that my method is wrong. My argument is the energy gained by the gas is equal to the difference in internal energy of the gas before heating and after heating.

Homework Statement A cylinder with a frictionless piston is placed horizontaly in an atmosphere of pressure 1.0×10^5N/m^2.A gas in the cylinder is initially at a temperature of 300K with a volume of 1.0 ×10^-3 m3.Then , the ags is heated slowly to a final temparature of 400k.How much work is...

Homework Statement An ambulance is moving in an expressway at a speed of 60km/hr from East to West(from A to B) as shown in the figure with a siren of 880Hz. Let the frequecies of the siren sound detected by an observer located at point O be Va and Vb as the ambulance just passes point A and...

I redid it. I got this: y+(1/4)a^2+a-3=(x-(1/2)a)^2 and solved a to be -6 or 2

Oh my mistake, I got this y+(1/4)a^2-3=(x-(1/2)a)^2 Is that what you have?

I get something to this effect; y+1/2a-3=(x-1/2a)^2 I get stuck because the y part cannot be factorized but I am again thinking that the I could equate 1/2a-3=0 because apparently the left side should not have a constant since the vertex is along the x-axis.That could give me one of the values...

Homework Statement When the parabola y=x^2-a(x+1)+3 intersects the x-axis at one point then a=_ or =_. Homework Equations The equation of parabola y^2=4px,x^2=4py depending on the orientation The Attempt at a Solution Since the parabola meets the x-axis once, I assume that to be the...
