Answer:
Therefore the required solution is

Explanation:
Given vibrating system is

Consider U(t) = A cosωt + B sinωt
Differentiating with respect to t
U'(t)= - A ω sinωt +B ω cos ωt
Again differentiating with respect to t
U''(t) = - A ω² cosωt -B ω² sin ωt
Putting this in given equation


Equating the coefficient of sinωt and cos ωt
.........(1)
and

........(2)
Solving equation (1) and (2) by cross multiplication method


and 
Therefore the required solution is

Answers with explanation
1)
Transmission
If all the light passes through a medium without any absorption then transmittance is 100%.
2)
Refraction
Refraction is the bending of a wave when it enters a medium where its speed is different and rays are again refracted when they leave that medium,
3)
Reflection
Reflected rays don't pass through the medium instead rays bounces off an object at an angle.

Hope that helps.
Power = Iω (constant) as they are connected together, since effort axle has large radius than resistance axle, so moment of inertia of effort axle is also more as compared to resistance axle, so angular speed of effort axle is less than the resistance axle. So answer is B. resistance axle will have more angular speed as its moment of inertia is less for the same power.
