Answer:
Making the crossing gate balanced makes the mechanical drive simpler and less expensive to operate.
Explanation:
See the attachment for a picture of what we're talking about.
The gate must be rotated up and down. That rotation is easier if the mass being rotated is balanced about the center of rotation. Less torque (and work) is required to create the desired motion.
Answer:
0.003181 radians
0.003005 radians
Explanation:
Number of slits = 140 /cm
λ = Wavelength = 434 nm = 434×10⁻⁹ m
m = 3 Third order spectrum
Space between slits
Now,
0.003181 radians
When λ = 410 nm = 410×10⁻⁹ m
0.003005 radians
