PHYS 325 Lecture 5: Lecture 5

When the first law of thermodynamics is applied to an ideal gasthat is taken through an isochoric process,
a. w = 0
b. delta u = 0
c. q = 0
d. none of the above

Prove the following expression. Explain allsymbols: (Ig=km/a)
m= #of divisions between 0 and M
k= galvanometer constant
Ig= current going through galvanometer

Part B)

Derive Expression: I=((Rg+Rs)/(Rs))Ig
Rg= resistance in galvanometer coil
Rs= shunt resistance

Part C)

Prove That if Ig is equal to the current across R1/2 then Rg=R1/2

How do the speeds v0, v1, and v2 (at times t0, t1, and t2) compare?

a: v0 = v1 = v2 > 0
b: v0 = v2 > v1 = 0
c: v0 = v2 > v1 > 0
d: v0 > v1 > v2 > 0
e: v0 > v2 > v1 = 0
