Answer:
Explanation:
The relationship between angle and wavelength for maxima and minima in Young's double slit experiment is given by
For constructive interference

For Destructive interference

where 

m=order of maxima and minima
for second order maxima i.e. 
For smallest separation taking 



Acceleration is a derived unit because it is derived from two quantities : Velocity and time.
We know, acceleration = Change in velocity/Time
The kinetic energy of the wind ==> causes ==>
the windmill to turn (mechanical energy) ==>
which is used to turn an electric generator ==>
which generates electrical energy.
Heat will be produced because of the friction from the tires
