Answer:
Angle of first order maximum, 
Explanation:
Given that,
Wavelength of the light, 
Number of lines, N = 8000 per cm
The relation between the number of lines and the slit width is given by :
The equation of grating is given by :
n = 1
So, the angle of the first-order maximum is 21.19 degrees. Hence, this is the required solution.
Mass is indirectly proportional to gravity, as moon has less gravity mass would be greater there, if weight of the object is same!
In short, your answer would be "Moon"
Hope this helps!

Answer:
0.25714 m/s
Explanation:
= Mass of 45 kg skater
= Mass of 60 kg skater
= Speed of 45 kg skater
= Speed of 60 kg skater
As the momentum is conserved
= Relative speed = 0.6 m/s
The speed of the 60kg skater is 0.25714 m/s
