Answer:
= 403 nm
Explanation:
We have the condition for the maximum for a diffraction grating
d sinθ =mλ
Then the grating constant d = w/N
= (75 mm)/(50,000)
= 0.0015 mm
Then wavelength of light is λ = (dsinθ)/m
= (0.0015 mm)(sin 32.5)/2
=403*10-6 mm
= 403 nm

Answer:
The total current supplied by the source of voltage = 10.29 A
Explanation:
We have a 14-Ω coffee maker and a 14-Ω frying pan are connected in series.
Effective resistance = 14 + 14 = 28Ω
Now we have 28Ω and 20Ω in parallel
Effective resistance

So we have resistor with 11.67Ω in a 120 V source of voltage.
We have equation V = IR
Substituting
120 = I x 11.67
I = 10.29 A
The total current supplied by the source of voltage = 10.29 A
its because it allows modern astronomers the ability to see farther out and more accuratly
It takes the moon about 27 days to revolve on its axis.
