Answer:
d = 8.4 cm
Explanation:
In order to calculate the amplitude of oscillation of the top of the building, you use the following formula for the max acceleration of as simple harmonic motion:
(1)
A: amplitude of the oscillation
w: angular speed of the oscillation = 2f
f: frequency = 0.17Hz
The maximum acceleration of the top of the building is a 2.0% of the free-fall acceleration. Then, you have:
Then, you solve for A in the equation (1) and replace the values of the parameters:
The total distance, side to side, of the oscilation of the top of the building is twice the amplitude A. Then you obtain:
d = 2A = 2(4.2cm) = 8.4cm

Answer:
Explanation:
Energy is directly proportional to frequency and it is given as:
E = hf
where h = Planck's constant
f = frequency
To get frequency, we use the formula of speed:
c = λf
where c = speed of light
λ = wavelength
=> f = c/λ
Therefore, the energy of the photon will be:
E = hc/λ
The energy of the photon is
