Answer: Inertia
Explanation: Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion.
Answer:
The minimum thickness of the material is 114.5 nm
Explanation:
The remaining part of the question is as follows
What should the minimum thickness of the material be for it to be nonreflecting for light of wavelength 600 nm (in a vacuum)? Please give details of your reasoning.
Both reflections occur against a surface of higher index of refraction, so there is a phase shift at each reflection. The phase shifts cancel each other out, so if we want the emerging rays to be out of phase, we must have
Given
Index of refraction = 1.31
Index of refraction = 1.43
As we know
Here t is the thickness
represents the phase shift
n is the refraction index
Substituting the given values we get
nm
The answer here would be infrared waves. Hot objects and humans give off heat in the form of infrared light, thermal imaging technology in the goggles enable them to catch this light emitted by these objects
Note that the density of mercury is
(i) 13545 kg/m^3 at 20 deg.C
(ii) 13472 kg/m^3 at 50 deg, C
For a given mass, M kg, by using the volume at 20 deg. C, obtain
M = (13545 kg/m^3)*(0.002 m^3) = 27.09 kg .
Let V m^3 = volume at 50 deg. C
Then
(13472 kg/m^3)*(V m^3) = 27.09 kg
V = 27.09/13472 = 0.002010837 m^3
Answer:
The closest answer is A. 0.002010812 m^3
