Anegatively charged rod is placed near two neutral metal spheres, as shown below. which statements describe the charging method shown? check all that apply.

the spheres develop opposite charges.
the spheres develop the same charge.
electrons move from the rod to sphere a.
electrons move from sphere a to sphere b.
the spheres are charged through conduction.
the spheres are charged through friction.
the spheres are charged through induction.

Correct answer choices are:

A. The spheres develop opposite charges.

D. Electrons move from Sphere A to Sphere B.

G. The spheres are charged through induction.

Explanation:

If a negative object is utilized to energize a neutral thing, then both objects become energized negatively. In order for the neutral ball to convert negative, it must obtain electrons from the negatively energized rod. A neutral metal ball is affected by a positively charged metal rod.

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
