i know it becomes 1000(50)/ 15 but i don't know where the 1000 came from. can someone please help?

is it ln 42.8= 1.4? but then what do i solve?

Homework Statement When a 50 N stone is attached to a spring scale and is submerged in water, the spring scale reads 35 N. What is the density of the stone? Homework Equations The Attempt at a Solution I found that the buoyant force is 15 N but i don't know what to do after. Can...

i get Vc^1.4= 42.8 how do i solve that? can anyone else help?

i get y= 1.4 then what do i do?

and then what do i do? can you show me please?

so Cp/Cv= 7/2R divided by 5/2R? where R is .08?

I don't know what equations and how do they relate? by going back to a via adiabatic process doenst that mean no heat is transferred?

yes i found the temp of A and B because they are the same since they are isothermal. knowing that i could find the Pressure of B and C because they are isobaric, but i can't find the volume or temp of point C.

Well the problem is One mole of a diatomic ideal gas has a pressure of 8atm and a volume of 3 L at point A. The gas is then expanded isothermally to point B where the volume is 12 L. The gas is then compressed isobarically to point C. the gas is returned to point A via an adiabatic...

i used the PV= NRT I can't find the Volume and Temperature of point C only.

Homework Statement The problem is on the attachment. I can't seem to find the volume or temperature of T. If someone can tell me how to find them i can do the rest of the problem. Any help would be greatly appreciated. Homework Equations The Attempt at a Solution on the attachment

i don't see how you get 0 can you explain please by showing the work. it would be greatly appreciated.

i use the mv=mv+mv formula right then what?

can you please just show me how its done. thanks
