Answer:
They are gaining energy, can move and slide past each other.
Explanation:
Because as ice melts, the molocules gain energy/heat which warm them up and are able to slide/move apart from each other.
Answer:
See attached handwritten document for answer
Explanation:
Answer:
19320 K
Explanation:
The temperature of a star is related to its peak wavelength by Wien's displacement law:

where
T is the absolute temperature at the star's surface
is Wien's displacement constant
is the peak wavelength
Here we have

Substituting into the equation, we find

At the instant the second bulb is connected ...
... the brightness of the <u>first bulb</u> doesn't change
... the brightness of the <u>second bulb</u> changes from dark (no brightness) to equal to the first bulb
Answer:
a) It moved to a lower potential
b) ΔФ = - 86.28 Volt
Explanation:
The energy of an charged particle and the electric potential are related by the potential al kinetic energies:

If we consider an electron:
m = 9.10938*10^-31 Kilogram
e = 1.60218*10^-19 Coulomb
And the potential diference may be calculed by:

Replacing all the values we get:
ΔФ = - 86.28 (Kilogram Meter^2)/(Coulomb Second^2) = -86.28 Volts
