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:
7 km
Explanation:
Okay so an hour is 60 mins, so
60/ 12 = 5
35/ 5 = 7
7 km
Vs = 34m/s
I don’t have an explanation my apologies.
Answer:
a. Ssystem > 40 J/K
Explanation:
Given that
The entropy of first block = 10 J/K
The entropy of second block = 30 J/K
When two bodies come into contact with each other, the entropy of the combined system will increase and the entropy sum remains unchanged: According to the Second law of thermodynamics.The entropy of the system will be greater than 40 J/K.
Therefore the answer is a.
Ssystem > 40 J/K
It will be potential because the roller coaster is going down so it’s not giving off energy to the roller coaster.
