Answer:
The minimum thickness = 83.92 nm
Explanation:
The relation between the wavelength in a particular medium and refractive index 
where ;
= wavelength of the light in vacuum
n = refractive index of medium with respect to vacuum
For one phase change :
Replacing 1.43 for n and 480 nm for λ; we have:
t = 83.92 nm
Thus; the minimum thickness = 83.92 nm
D is the answer! Hope it helps
Depends on the mass of the projectile versus the object.
The force of gravity is dependent upon the mass of the object. Therefore if the mass of the projectile and the mass of the object are exactly the same than both objects will fall at the same rate and will collide. If the mass of the object is significantly larger than it will fall faster and the projectile will pass above it. The opposite is true if the mass of the object is less than the mass of the projectile, in which case the projectile will pass underneath.
Lastly, this analysis excludes the force of wind resistance on the projectile and the object. Under a complex model how the projectile travels through the air will have a separate impact that will alter its decent or rise outside of gravity. For example, if the projectile is spinning it could "cut" into the wind and cause accelerated drop. Think of a curve ball in baseball or a rising fastball.
