Answer:
The average power is 15.26 W.
Explanation:
Given that,
Force = 29 N
Radius = 0.27 m
Time = 1.9 s
We need to calculate the power
Using formula of power
Here,
Where, F = force
t = time
r = radius
Put the value into the formula
Hence, The average power is 15.26 W.

Answer:
Approximately 3 photons
Explanation:
The energy of a photon at the peak of visual sensitivity is given by:
where
h is the Planck constant
c is the speed of light
is the wavelength of the photon
Substituting into the formula,
This is the energy of one photon. The human eye can detect an amount of energy of
So the amount of photons contained in this energy is
so approximately 3 photons.
