Answer:
3.28 degree
Explanation:
We are given that
Distance between the ruled lines on a diffraction grating, d=1900nm=
Where
We have to find the angular width of the gap between the first order spectrum and the second order spectrum.
We know that
Using the formula
m=1
Now, m=2
Hence, the angular width of the gap between the first order spectrum and the second order spectrum=3.28 degree

Answer:
e=58%
Explanation:
Given data
The Otto-cycle engine in a Mercedes-Benz SLK230 has a compression ratio of 8.8.
Solution
We want to calculate the ideal efficiency of the engine when ratio of heat capacity for gas used γ=1.40. Ideal efficiency (e) of the Otto cycle given by:
Substitute the given values to find efficiency e
e=58%
