You've recently read about a chemical laser that generates a 20.0-cm-diameter, 26.0 mw laser beam. one day, after physics class, you start to wonder if you could use the radiation pressure from this laser beam to launch small payloads into orbit. to see if this might be feasible, you do a quick calculation of the acceleration of a 20.0-cm-diameter, 90.0 kg, perfectly absorbing block.
what speed would such a block have if pushed horizontally 100 m along a frictionless track by such a laser?

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback

1kg of water needs to recieve 4200j of energy to go from 90 degrees to 91 degrees. what is the specific heat capacity of water? what are the units?

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
