Answer:
we do not exceed that value, the force of having a value less than that calculated
Explanation:
Pressure is defined by
P = F / A
F = P A
F = 180 10⁶ A
for an exact calculation the area of the wire is needed
So that we do not exceed that value, the force of having a value less than that calculated
therefore the correct answer is "a smaller value"
Answer:
T = 0.638 s
Explanation:
vmax = Aω
ω = 7.02/0.713 = 9.8457 rad/s
T = 2π/ω = 2π/9.8457 = 0.63816
The only common property is that both of those things are comprised of H2O.
Answer:
The blue light has the highest energy.
Explanation:
Body that is hot enough emits light as consequence of its temperature. For example, an iron bar in contact with fire will start to change colors as the temperature increases until it gets to a blue color. That its know as Wien's displacement law, which establishes that the peak of emission for the spectrum will be displaced to shorter wavelengths as the temperature increases.
The same scenario described above can be found in the star, a star with higher temperature will have a blue color and one with lower temperature will have a red color.
(1)
The energy of each wavelength can be determined by means of the following equation:
(2)
but
, therefore:
(3)
Where h is the planck's constant and
is the frequency.
Notice that it is necessary to express the frequency in units of meters for a better representation of the energy.
⇒
⇒
Case for the bluest light:
Case for the reddest light:
Equation 3 show that if the wavelength is lower the energy will be greater (inversely proportional).
Hence, according with the result and what was explained above, the blue light has the highest energy.
