Remember that an atom is made up of three subatomic particles: Protons - located in the nucleus with a +1 charge and a mass of approximately 1 amu. WebSolar wind (radiation) that is incident on the top of Earth’s atmosphere has an average intensity of 1.3 kW / m 2. 1.3 kW / m 2. Suppose that you are building a solar sail that is to propel a small toy spaceship with a mass of 0.1 kg in the space between the International Space Station and the moon.

WebThere is no mass or charge in a photon. An electric field and a magnetic field do not reflect photons. ... For a given metal, the photoelectron’s maximum kinetic energy is solely determined by the incident light’s frequency. The work function is the amount of work that must be done in order for a metal to emit a photoelectron. Web25 de mar. de 2015 · The power absorbed by the photo-cathode is Pc = 0.540 W, but only 0.2% of this incident energy is effective in producing photoelectrons. I have no clue how i didn't realize the rate of emission is right there. Current I = power W / voltage V So would this calculation be correct? I = (0.540 x 0.2) / 2.2 = 0.049 amps? they\u0027re always watching meme
