An object is held at rest and allowed to drop How far does the object fall in 3.3 seconds?
IgorC [24]
After x seconds, an object will fall \frac{1}{2}at^2 where a is acceleration due to gravity and t is time

so when t=3.3
the distance it will fall is (\frac{1}{2})(9.8\frac{m}{s^2})(3.3m)^2=53.361m
it will fal 53.361 meters

The nonreflective coating on a camera lens with an index of refraction of 1.29 is designed to minimize the reflection of 634-nm
eimsori [14]

Answer:

minimum thickness of the coating = 122.868 nm

Explanation:

Given data

lens index of refraction = 1.29

wavelength = 634 nm

glass index of refraction = 1.53

to find out

minimum thickness of the coating

solution

we have given non reflective coating

so

we know that minimum thickness of the coating formula

minimum thickness of the coating = Wavelength / 4n

here n is coating index of refraction

so put here both value to get thickness

minimum thickness of the coating = Wavelength / 4n

minimum thickness of the coating = 634 / 4 ( 1.29 )

so minimum thickness of the coating = 122.868 nm
