Abeam of light hits a sheet of metal. if it has enough energy, electrons break free from the metal sheet.
which choice correctly describes the behavior of light in this situation?

in this situation, light behaves as a particle colliding with another object. this is because increasing the energy in the light beam releases more electrons from the metal, but does not increase the energy carried by each electron.

in this situation, light behaves as a particle colliding with another object. this is because increasing the energy in the light beam increases the energy carried by each electron but does not increase the number of electrons released.

in this case, light acts like a wave because it requires the total energy of a wave to dislodge the electron. increasing the energy in the light beam releases more electrons and increases the energy carried by each electron.

in this case, light acts like a wave because it requires the total energy of a wave to dislodge the electron. increasing the energy in the light beam doesn’t releases any more electrons but it does increase the energy carried by each electron.

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

happy to

pls mark as brainliest.

answer: strength i guess

explanation:

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it

hope this
