Applying diffraction equations;
d = 0.01/Number of lines; where 0.01 m = 1 cm, and d = spacing between lines
Therefore,
d = 0.01/2000 = 5*10^-6 m
Additionally,
d*Sin x = m*y; where x = Angle, m = order = 1, y = wavelength = 520 nm =520*10^-9 m
Substituting;
Sin x = my/d = (1*520*10^-9)/(5*10^-6) = 0.1040
x = Sin ^-1(0.104) = 5.97°
Therefore, first-order maximum for 520 nm will be 5.97°.
The mass of moon is 1/100 times and its radius 1/4 times that of earth as a result the gravitational attraction on the moon is about one sixth when compared to earth.
Answer:

Explanation:
From the question we are told that:
Height 
Radius 
Height of water 
Gravity 
Density of water 
Generally the equation for Volume of water is mathematically given by


Where
y is a random height taken to define dv
Generally the equation for Work done to pump water is mathematically given by

Substituting dv


Therefore
