Answer:
848.5 J
Explanation:
We are given that
Height,h=12 m
Force,F=110 N
We have to find the work done .
We know that
Work done,W=
Using the formula
W=
W=848.5 J
Hence,the work done=848.5 J
Answer:
572.3 nm
Explanation:
= refractive index of the oil film = 1.48
= thickness of the oil film = 290 nm
= wavelength of the dominant color
m = order
Using the equation
For m = 0
= 1716.8 nm
For m = 1
= 572.3 nm
For m = 2
= 343.4 nm
Hence the dominant color wavelength is 572.3 nm
