Okay, this is what I got, and I hope it's right:
F(13)=F(23)
GM1M3/(R13^2)=GM2M3/(R23^2)
M1/(R13^2)=M2/(R23^2)
2x10^30/(1.4x10^12^2)=M2/(1.0x10^11^2)
M2= 1.02x10^28
Was it okay to assume the distance from the probe to the sun is the distance from the planet to the sun- the...
F1,2=[(G *m1*m2)/(r1,2^2)]*r1,2
That's what it says in my book, it looks weird when you type it.
But I tried this problem another way, and tell me what you think:
I used t^2=Cr^3 compared to the Earth to get the period of the planet which I got was 6.53x10^15.
Then I used that in...
Space probe, planet, and sun...
Correcting test again, and I don't know where to start on this problem:
A space prob lies along a line between a planet and the sun so that the sun's gravitational pull on the probe balances the planets pull. The distance of the probe from the planet is 1.0...
Hi, everyone...we just got a test back and I'm correcting my problems so I have the right answers for the final...
An inert physics student slides down a plane inclined at 20 degrees above the horizontal. He feels a constant retarding friction force of 100 N as he slides 10 m down the plane...
One more question:
2Al+3FeO=3Fe+Al2O3
When I am doing Mass to Mass ratio, I would do #g Al/ molecular weight Al x 2
for example if I am reacting 468g Al, I put it over 54g Al, not just 27.
I hope that makes sense.
Consider this eq, It is balanced:
KCN+HCl=KCl+HCN
If a sample of 0.140g of KCN is treated with an excess of HCl, calculate the amount of HCN formed, in grams:
I just want to know if I did this right
0.140g KCN/65g KCN = x/27g HCN
and I got .058 g
Another probem:
Ammonium Nitrate...
Game Guru , I am correcting a test I have already had so I have it to study, and your answer is what I put on the test and got a 0/15...so it's not that.
This is what I'm thinking,
I use the Range formula:
range=initial velocity squared divided by g, and that multiplied by sin 2 theta...
Help with a problem!
This problem seems pretty easy but for the life of me I cannot get it, I think it's confusing me because I don't have a intial velocity or a time...help!
