Ohhh yea it was root(GM(planet A or B because they weighed the same)/x)

damn it I think I put a 2 in there

 

[Speed’o’sound Sonic]

Oh yeah I forgot that just now sorry I’m just remembering off the top of my head

wait so you did put a 2 in there

 

[Speed’o’sound Sonic]

Yeah I think, not too sure. I think the 2’s might cancel on Both sides bro.
K = 1/2 mv^2 = GmM/2r
They cancel I think

why was it 2r?

yeah the root2gm/r is escape velocity

 

[Speed’o’sound Sonic]

why was it 2r?

Uhhh cause that’s the equation for kinetic energy of an object in orbit

I just did Fcp=Fg where mv^2/r=Gm^2/r^2and got the same thing

 

[Speed’o’sound Sonic]

I just did Fcp=Fg where mv^2/r=Gm^2/r^2and got the same thing

Maybe I did that forreal I might have done that too, can’t remember rn but it’s good that we got the same answer

Yeah syrel

oh well I'll lose a mark for that nvm. hope 90 91 raw

 

[homeworkatedog]

Uhhh cause that’s the equation for kinetic energy of an object in orbit

f=mv2/r=GMm/r2
v2/r=GM/r2
v2=GM/r
v=sqrtGM/r

 

[Luke322]

sooo much blackbody omg in that paper

 

[Speed’o’sound Sonic]

f=mv2/r=GMm/r2
v2/r=GM/r2
v2=GM/r
v=sqrtGM/r

Correctamundo

 

[Luke322]

the blackbody curves had to not overlap i think. Still got it wrong tho haha

I think they were just looking for shifted down and to the right

 

[Luke322]

I think they were just looking for shifted down and to the right

hope so. oh yeah it was 2 marks for that and 2 marks explaining i think

 

[Luke322]

and the fission control rod question multi was the option which was with the coolant right?

 

[Speed’o’sound Sonic]

No it was remove the control rods

 

[Luke322]

No it was remove the control rods

WHAT

 

[Luke322]

But if you cool the temperature the neutrons would be slowed as their kinetic energy will decrease which accounts for removing the material
