A student is performing an experiment comparing sound and light waves. The student gathers the
following data.
What conclusion does the student most likely make
based on this data?

O Light waves always travel the same speed; however,
the speed of sound is determined by the medium
that it travels through.
O All sound waves always have the same energy, so
the temperature of the medium does not affect wave
speed.
O Light needs to vibrate particles, so it travels fastest
in tightly packed solids, while sound does not need a
medium, so it travels fastest in a gas.
O Tightly packed particles in solids slow down the light
waves, however, sound wavesmake particles
bounce into each other, so they travel faster in
solids.

-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

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

the answer is a. hope this .
