Ответ:
t = ( 12 N ) ( 0 m ) ( cos 30 ) + ( 12 N ) ( 1.68 m ) cos 45
t = 14.26 Nm is the torque with respect to the hinge
Ответ:
The limiting angle is 7.32x10⁻⁸rad and the separation distance is 8.586x10⁹ rad m
Explanation:
Given data:
λ = 600 nm = 6x10⁻⁷m
D = 10 m
The limiting angle of resolution is equal to:
According Rayleigh expression:
L = 12.4 light year = 1.173x10¹⁷m
