WebWe know that the Sun loses 3.78 x 10 26 Joules of energy every second (this is the Sun's luminosity). By using E = mc 2, figure out how much mass this corresponds to. That is, how much mass does the Sun lose every second? Express your answer in metric tons. (A metric ton = 1000 kg.) (2 pts.) WebNone would exist without it. At the Earth's orbit, neglecting absorption by the atmosphere, each square meter of area facing the Sun receives about 1380 joules per second (nearly …

29.3 Photon Energies and the Electromagnetic Spectrum

WebPower is energy per unit time, and so if we can find the energy per photon, we can determine the number of photons per second. This will best be done in joules, since power is given in watts, which are joules per second. Solution The power in visible light production is 10.0% of 100 W, or 10.0 J/s. WebThis means, the energy emitted in one second = 25 × 10^ {-3} 25×10−3 J Number of photons in one second = \dfrac {25×10^ {-3}} {3.74×10^ {-19}} = 6.68 × 10^ {16} 3.74×10−1925×10−3 = 6.68×1016 Need a fast expert's response?

How Much Energy Does the Sun Produce? - Solar Reviews

WebIncandescent light bulbs radiate 40 to 100 watts. The Sun delivers 1,360 watts per square meter. An astronaut facing the Sun has a surface area of about 0.85 square meters, so he or she receives energy equivalent to 19 60-watt … Web18 jan. 2024 · The sun produces 1.23 x 10 ^ 35 Joules of energy in one year. To compare, a nuclear weapon only gives off 4.18 x 10 ^ 15 Joules of energy, which is less energy … WebLet's calculate the number of photons emitted per second from a 100 watt light bulb, and the no. of photons hitting the wall per second from a 5W/m^2 intensity laser light. … henry licett可播放怪几巴
