Installed on your roof is a solar panel that has a surface area of 1.00 m2 . How many photons from the Sun reach the panel? Assu

kirill115 [55]

Answer:

$3.95241\times 10^{21}\ Photons/second$

Explanation:

h = Planck's Constant = $6.626\times 10^{-34}\ m^2\kgs$

A = Area = 1 m²

Distance between Earth and Sun = $1.5\times 10^{11}\ m$

$\lambda$ = Wavelength = 580 nm

c = Speed of light = $3\times 10^8\ m/s$

Power output of Sun

$P=3.83\times 10^{26}\ W$

Intensity

$I=\frac{P}{4\pi d^2}\times A\\\Rightarrow I=\frac{3.83\times 10^{26}}{4\pi (1.5\times 10^{11})^2}\times 1\\\Rightarrow I=1354.5854\ W$

Energy of photons

$E=\frac{hc}{\lambda}\\\Rightarrow E=\frac{6.626\times 10^{-34}\times 3\times 10^8}{580\times 10^{-9}}\\\Rightarrow E=3.42724\times 10^{-19}\ J$

Number of photons

$N=\frac{I}{E}\\\Rightarrow N=\frac{1354.5854}{3.42724\times 10^{-19}}\\\Rightarrow N=3.95241\times 10^{21}\ Photons/second$

The number of photons are $3.95241\times 10^{21}\ Photons/second$

exis [7]

Answer:

Explanation:

electrical field strength = potential diff / distance

= ( 450 - 0 ) / 8 x 10⁻²

= 5625 V/m

b )

potential difference = electric field x distance

= 5625 x .10

= 562.5 V

The minimum voltage that is required to generate an action potential is called the _______.

allochka39001 [22]

The answer would be threshold voltage. It is the minimum value of voltage needed to produce an action potential. It is also known as gate voltage. It is the minimum value that would make turn a transistor on. Hope this answers the question.
