Answer:
7.894 Hours.
Explanation:
Based on information number hours that this battery will last with give load has mathematical relation of.
with load 60A t = 1h, 30A t = 2h so on and forth.
two head lights draw total current of 2x3.8A = 7.6A.
putting this in above relation gives.
.
That is how long will it be before battery is dead.
The irradiance of the sun dependent on the wavelength of the radiant energy it emits.
<h3>
What is irradiance of the sun?</h3>
The solar irradiance is the output of light energy from the entire disk of the Sun, measured at the Earth.
The energy output is given as;
E = hf
E = hc/λ
where;
- c is speed of light
- f is frequency of the light
- λ is wavelength of the light
Thus, we can conclude that the irradiance of the sun dependent on the wavelength of the radiant energy it emits.
