In my attempt, I tried
1) I1 = I2 + I3
Then set up these two equations based on Kirchhoff's second rule:
2) U1 = R1 (I2) + R3 (I3) and
3) U1 + U2 = R1 (I1) + R2 (I3).
From what we have
10 = 0.1* I_2 + 0.2 * I_3
22 = 0.1* I_2 + 0.02*I_3
I_3 = 50 - 0.5 I_2
That means
I_2 = 233.3 A
I_3 = -66.7A...
Homework Statement
A star moves away from us at a speed of 10 km / s. the angle between the speed direction and the line of sight are 30 °. What is the observed wavelength of the Hα line?
Then we suppose the observer is also moving at a speed of 20 km / away from the star.
What is the observed...
Homework Statement
λ = 240 nm
D = 2.40 m
We are supposed to find the angle resolution (minimum angular distance between two objects so we
still see them as two separate objects) to the telescope for ultraviolet light with wavelength 240 nm
