Answer:
2.7 J
Explanation:
The energy of one photon is given by
where
h is the Planck constant
f is the frequency
For the photons in this problem,
So the energy of one photon is
The number of photons contained in 1.0 mol is
(Avogadro number)
So the total energy of photons contained in 1.0 mol is
It will decrease the biodiversity due to an invasive species coming in and messing up the ecosystem (the last answer). This isn't a physics question tho lol
<h2>ANSWER:</h2><h2>
_____________________________________</h2>
<u>DATA</u>:
m = 0.05 kg
Vf = 10 m/s
Vi = -10 m/s
t = 4 times hits in 2 second
<h2>_____________________________________</h2><h3><u>SOLUTION</u>:</h3>
The momentum ρ is given by,
ρ = mV
where,
m = mass
V = velocity
<h2>_____________________________________</h2>
The Equation for average force is given by,
F = Δρ/Δt
where,
Δt = time taken
Δρ = change in momentum. Which is given by,
Δρ=
Vf = final velocity which is the rebound velocity here
Vi = Initial velocity which is the velocity before striking the wall
So Substitute the equation of momentum in the equation of force
F =
<h2>_____________________________________</h2><h3>SUBSTITUTING THE VARIABLES IN THE EQUATION</h3>
F =
F =
F =
F =
F = 0.5N
<h3>__________________________________________________</h3><h2>0.5 NEWTON is the average force on the wall</h2><h2>_____________________________________ </h2>
Wavelength i’m assuming that would be the most reasonable
