In order for the statement to be complete, the word needed is the interferometer. It is an optical device whose application is to make to ray beams from the single beam of light. It is usually in the form of reflection to produce interference.
Answer: v = 3.684 m/s
Explanation: The angular frequency (ω) of a loaded spring is given as
ω = √k/m
Where ω = angular frequency, k =spring constant = 11.9 N/m, m = mass of object = 40.1 g = 0.0401 kg.
The velocity of a simple harmonic motion is defied as
v = ω√A² - x²
Where A = Amplitude = 24.7cm = 0.247m and x = displacement.
For our question, we where asked to find velocity at half way, at half way, x = A/2
Hence at half way, x = 0.247/2 = 0.1235 m.
We need to get the value of angular frequency first.
ω = √(11.9/0.0401)
ω = √296.758
ω = 17.22 rad/s.
Then the velocity is
v = 17.22 √0.247² - 0.1235²
v = 17.22 √0.061009 - 0.01525225
v = 17.22 √0.04575675
v = 17.22 × 0.2139
v = 3.684 m/s
Answer: C
produces as much as or more energy than it uses
Explanation:
This implies that the total energy used by the building is equivalent to the energy generated by the site
