Answer:
Explanation:
= Refractive index of bubble = 1.33
f = Frequency of light = 
c = Speed of light = 
The wavelength of light is given by
Wavelength is also given by
m = 1 for minimum thickness
The minimum thickness is
Answer:
Explanation:
radius of gyration of wheel k then
k² = r²/2
r² = 2 k²
r = √2 k
= 1.414 x .3 m
r = .4242 m
Moment of inertia of wheel
= mass x radius of gyration ²
= 25 x .3 x .3
= 2.25 kg m²
Friction force acting on it ( sliding )
= μmg , μ being coefficient of kinetic friction
This friction force will create linear acceleration in forward direction
Acceleration produced
= μg
= .6 x 9.8
= 5.88 m / s ²
This will also rotate the wheel , angular acceleration being
linear acceleration / radius
= 5.88 /.4242
= 13.86 radian / s²
Complementary is essentially two things that are "combined" with one another (complement one another) to make a bigger piece or make it better.
