E=ΦreceivedA
M=ΦemittedA
where A is the area of the surface in square meters (m2). Both irradiance and emittance are measured over an entire hemisphere, providing the total energy arriving at (irradiance) or leaving (emittance) a surface over all possible angles.
Question 15.
A. How much radiant energy does a 100 W bulb emit in 10 seconds? Show your work.
B. How many photons does it emit in in that same time frame? Show your work.
C. What is the emittance of a 50 W energy source that is 10 x 10 m in size?
D. How much irradiance would a 10’ x 10’ solar panel receive over the course of one hour, assuming a 100 J solar energy source? Show your work.
This is all the information I was given and I don't know how to figure it out

At a certain location, the solar power per unit area reaching the Earth's surface is 210 W/m2 averaged over a 24-hour day. Suppose you live in a solar powered house whose average power requirement is 3.2 kW. At what rate must solar energy reach your solar panels if your solar panels have a typical coversion efficiency of 13 %. (In other words, what power must your solar panels receive?) Answer in both kiloWatts and Watts. Psolar = Psolar = Based...

Temperatures on planets. To a good approximation, stars and planets emit their energy like a black body, which means the energy flux (energy per unit area and per unit time) at the solar surface (radius R_s = 7 times 10^8 m) is given by F = sigma_SBT^4, where sigma_SB = 5.67 times 10^8 W m^-2 K^-41 is the Stefan-Boltzmann constant. [Remember, energy per unit time is power and it- is...

1. In the figure below, a solution containing lung extract
exhibits hysteresis in is surface tension versus area relationship.
This means the surface tension is higher during inflation of the
lung than deflation.
