power emitted by helium. Neon laser equals 2.2 million votes, so power equals 2.2 million watts. To point to Millie walks, 2.2 million watts equals two point toe multiply by Ah Dante Power minus tree Jewell were second rental put own lender equals 6 32.8 nanometers, 6 32 point it mana meters 6 32.8 nanometers equal. Ah, 6 32.8 Multiply by 10 to the power minus my leaders, and we have energy. Your foot on e equals X times see Divided by Lambda H blanks, constant is equal to 6.63 Multiply by 10 to the power minus 34 multiplied by see speed off light. Three. Multiply by 10 to the power it divided by Linda is 6 32 point and multiply by 10 to the power minus line and solving this will be had equals 3.1 3.1, multiplied by 10 to the power minus 19. Jules Dan, Teri Bauer minus 19 Jules. Number of photons emitted per second by William Me on leather. Um, so a number or for tones? Four dawns. Emitted per second imitated per second for a second equals 2.2. Multiply by 10 to the power minus three, divided by 3.1. Multiply by 10 to the power minus 19. Dividing the numbers we get 7.1 7.1, multiplied by 10 30 Power 15 4 Don&#x27;t stand to the power 15 four tones So number of photons emitted per second is 7.1, multiplied by 10 to the power 15 for tones. No, let&#x27;s do part B this WAAS uh, part, eh? No Lex to part B. We know that Sequels F Lando F Lambda therefore f pickles tree multiply by 10 to the power eight Divided by lender is are 632.86 chri I do point it multiply by 10 to the power minus nine Dividing the numbers f equals 4.7 4.7 multiplied by 10 to the power 14 hearts

Salamat Ali · Answer

in this problem, we are asked how many four tones per second are emitted by 7.50 minute World&#x27;s CEO to laser that has a revenant offer. 10.6 micro uh, micro meter. We can find it by first finding the energy off a photo The energy photon is given by age divides each time CD by the Lambda sub strutting around in 64626 times 10 to the power minus 34 June 2nd downs three time standing Our eight divided by Lunda That is 10.6 times 10 to the power minus six Reader excuse us. Energy off for tone to be for dawn. Foretold to be 1.874 time standing power minus 20. Jules womb, we can write a power than our baby energy for unit down. Um, them from here energy total total energy will be 7.5 times 10 to the power minus three jewels for each second for second, then energy. Total total is ah a number of four times per second times energy over each for food, so tone from here and will be key total He total divided by energy off each for prom, hoping this gives us so by substituting value. Same. 1.5 times. Temple power minus three jewels divided by 1.874 towns. Gentle power minus 20 Jones Excuse US four times 10 to the power 17 four bones. Photos for a second.

Ren Jie Tuieng · Answer

this could Looking at a 7.5 me. What visa? No, one of fine. How many four times are being Mito? Pull a second. So given debt you everything off the media Photons is 10.6 micrometers and this is T energy release. Pull a second Can find what? STD total number photons space on the energy or the force? Yes. We need to find FirstEnergy only four time given, etc. See over Lunda elevating. This should get about 1.87 four stand po minus 20 juice, please. Energy off each photon energy least by u ni za. Put a second. Yes. So 0.5 extensible ministry juice. Right. This is because it&#x27;s really what&#x27;s that was his just juice for second. Therefore, t number off. Four taunts least pull second. It&#x27;s just taking the energy told energy per second Developed by the energy for each photon. Yeah, Be sure it gets both full percent poll of 17 four tons. More photos released. Will you meet its second

Mayukh Banik · Answer

energy for the Fortune is given by H. Seal. A Lambda equals 6.626 times 10 June 18 34. Time See on the website is 6 33 d animated. It was reported one times 10 to the negative. 19 jewels. Now number off four guns and we get for a second is given by power over energy. It was 10 to the minus three. What? Or let&#x27;s not put the unit in 10 to the minus three. What is our one million work? Divided by 3.1 times 10 to the ladies 19. It was 3.2 times 10 to the

Ren Jie Tuieng · Answer

use caution would give any carbon dioxide later. We have power off 7.5. Really? What&#x27;s and that the photons have wavelength off. Tempering six Michael meters six stent. Momentous six You gotta find when you see number four ones in meters per second. So the energy meet its 1st 2nd? Yes, 7.5% of always tree juice. You know, the energy body fort on you can find by figuring each see my Lunda and we forget about 1.874 Step over this training juice and using this you can and find the number four tots Number four tons would just be taking it also energy. You took support. Second, if I buy the energy for each fort on, they should give us full points. You timestamp. 07 teeth. So these number 4 20 m for a second

Ronald Prasad · Answer

how many photons per second is the laser Admit, we&#x27;re told that the laser has a wavelength of 630 nanometers, and that is emitting one wat, which is also equivalent of one jewel per second. So the energy of the photon emitted people. That HC over Lambda H is Planck&#x27;s constant Cesar speed of light. Yeah, and the wavelength. 630 times 10 to the minus 9 m. We find that the energy of the photon works out to 3.15 times 10 to the minus 19 jewels. Now, the number photons released per seconds would be called to one jewel per second over 3.15 times 10 to the minus 19 jewels, and we find that this is equal to 3.17 times 10 to the 18th mm photons per second.
