Answer:
A. evaporation
Explanation:
Evaporation is a surface phenomenon as the molecules of the surface gets sufficient energy to overcome the force of attraction which will help in converting to the vapor phase.
A voltmeter is the instrument used to measure a potential difference between two points in an electric circuit
I believe that the price will rise.
Hope this helps!
Answer:

Explanation:
Potential energy is minus the integral of Fdx. Doing the integration yields:



so


Now for x=3.0m


Answer:
1449 K
Explanation:
The surface temperature of a star is related to its peak wavelength by Wien's displacement law:

where
T is the surface temperature
b is Wien's displacement constant

So the surface temperature of the star is
