Science question!
which of these is the best explanation for why two negatively charged balloons move apart without ever touching? a. charger objects send little lighting bolts of electrons across the space between the two balloons. b. electrons from one balloon jump to the other and push it, without ever touching it. c. electronic charges have electric fields surrounding them that allow them to exert forces on other objects without touching them. d. the space between objects is actually filled with charged particles that all intersect.

C. Electronic charges have electric fields surrounding them that allow them to exert forces on other objects without touching them.

Explanation:

All the electric charges have electric field in the region surrounding them

This electric field is given as

above formula is the electric field due to a point charge in the surrounding region of it.

Now due to this electric field when other charges comes into this region they will experience electric force on them which is given as

due to above reason two charges either attract or repel each other

so correct answer will be

C. Electronic charges have electric fields surrounding them that allow them to exert forces on other objects without touching them.

-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
