1. 
The frequency of a photon is given by:
where
c is the speed of light
is the wavelength
The wavelength of the photon in this problem is
So, the frequency of the photon is
2. 
The energy of a photon is given by
where
h is the Planck constant
f is the frequency of the photon
The frequency of the photon in this problem is
so its energy in Joules is
And since
The energy in eV is
The answer: 3.00 * 10 ⁸ .

By the newtons Second Law:
F = ma
Solving for m:
m = F / a
m = 100 N / 2 m/s²
<h3>m = 50 kg → ANSWER</h3>

Answer:
P V = n R T ideal gas equation
P2 V2 / P1 V1 = T2 / T1
V2 / V1 = T2 / T1 * P1 / P2 = T2 P1 / (T1 P2)
V2 / V1 = (1.17 T1) / T1 * (P1 / .22 P1) assuming absolute temp as 1.17 P1
V2 / V1 = 1.17 / .22 = 5.32
V = 4/3 pi R^3 = 4/3 pi (D/2)^3 = 4/3 pi D^3 / 8 = pi D^3 / 6
V2 / V1 = D2^3 / D1^3
D2 = (V2 / V1 * D1^3)^1/3
D2 = 5.32^1/3 * D = 1.75 D (D1 = D)
