Answer:
i would have to add and divide
Explanation:
adding and dividing will get you the answer
15 ppm
1.5 × 10-2 ppm
1.5 × 104 ppm
3.1 ppm
1.5 × 10-2 ppm
The energy of a photon : 7.645 x 10⁻³⁴ J
<h3>Further explanation
</h3>
Radiation energy is absorbed by photons
The energy in one photon can be formulated as
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
f = c / λ
, Hz
c = speed of light
= 3.10⁸ m/s
λ = wavelength
,m
wavelength λ of 2.60 ✕ 10⁻⁸ m
The energy :
Answer:
= 18.75 L
Explanation:
Using the combined gas law;
P1V1/T2=P2V2/T2
Where; P1 is the initial pressure, 0.25 atm
V1 is the initial volume 300.0 L
T1 is the initial temperature, 400 K
P2 is 2 atm and
T2 is 200 K
Therefore;
(0.25 × 300)/400 = 2V2/200
V2 = (75 ×200)/(400×2)
= 18.75 L
Assuming that the proton is in the shape of the sphere, let's calculate first its volume in units of cm³:
Volume of sphere = 4/3*πr³
Volume of sphere = 4/3*π{[(1.0×10⁻¹⁵ m * 100 cm/1m)]/2}³
Volume = 5.236×10⁻⁴⁰ cm³
The density is then equal to:
Density of proton = 1.0073 g/5.236×10⁻⁴⁰ cm³
Density = 1.924×10³⁹ g/cm³
