Describe how the number of photoelectrons emitted from a metal plate in the photoelectric effect would change if the following occurred.(a) the intensity of the incident radiation were increasedAs long as the radiation has a frequency above the cutoff value, the greater the intensity the larger the flux of photoelectrons that flow off of the metal plate. If the frequency of the light is below the cutoff, it does not matter how much the intensity is increased. No photoelectrons will be emitted. As long as the radiation has a frequency above the cutoff value, the greater the intensity the lower the flux of photoelectrons that flow off of the metal plate. If the frequency of the light is below the cutoff, it does not matter how much the intensity is increased. No photoelectrons will be emitted. As long as the radiation has a frequency below the cutoff value, the greater the intensity the larger the flux of photoelectrons that flow off of the metal plate. If the frequency of the light is above the cutoff, it does not matter how much the intensity is increased. No photoelectrons will be emitted. none of these(b) the wavelength of the incident radiation were increasedIf the wavelength is increased, the energy of the radiation will decrease. If it slips above the work function of the metal plate, the photoelectric effect will cease. none of theseIf the wavelength is increased, the energy of the radiation will decrease. If it slips below the work function of the metal plate, the photoelectric effect will cease. If the wavelength is increased, the energy of the radiation will increase. If it slips below the work function of the metal plate, the photoelectric effect will cease.(c) the work function of the metal were increasedIf the work function of the metal is increased, it will eventually grow past the energy of the incident photons and the effect will intensify. The flux of photoelectrons that flow off of the metal plate will decrease gradually as the work function is increased. There will be no change in the effect if the work function of the metal is increased. If the work function of the metal is increased, it will eventually grow past the energy of the incident photons and the effect will cease

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?

Which sentences describe point source pollution? in this type of pollution, the source of the pollution is single and easily identifiable. when runoff water from the melting of snow mixes with debris, it creates pollution. the runoff water, mixed with pollutants, reaches large areas with disastrous effects. alternatively, when a wastewater treatment plant releases harmful chemicals into a stream, the chemicals pollute the stream water because they are not treated for safety.
