Correct me if I’m wrong but I think it’s C
Answer:
true
Explanation:
takes time for most plates to move but throughout time they keep moving just at a slow pace
Answer:
The wavelength of the station’s signal is 2.9 meters
The energy of a photon of the station’s electromagnetic signal is 
Explanation:
Wavelength 
is inversely proprtional to frequency (f) and directly proportional to velocity of the wave (v).
(1)
But electromagnetic waves as radio signals travel at speed of light so using this on (1):
Albert Einstein discovered that energy of electromagnetic waves was quantized in small discrete packages of energy called photons with energy:
with h the Planck's constant.
Answer:
the answers the correct one is cη
Explanation:
In this simple pendulum experiment the student observes a significant change in time between each period. This occurs since an approximation used is that the sine of the angle is small, so
sin θ = θ
with this approach the equation will be surveyed
d² θ / dt² = - g / L sin θ
It is reduced to
d² θ / dt² = - g / L θ
in which the time for each oscillation is constant, for this approximation the angle must be less than 10º so that the difference between the sine and the angles is less than 1%
The angle is related to the height of the pendulum
sin θ = h / L
h = L sin θ.
Therefore the student must be careful that the height is small.
When reviewing the answers the correct one is cη
