1. What is the primary difference between an ideal emf device and a real emf device? a) The electric potential of a real emf device is limited. b) The resistance of a real emf device is finite, but the resistance of an ideal emf device is assumed to be infinite. c) A real emf device can carry an electric current, but an ideal emf device does not. d) A real emf device has an internal resistance, but an ideal emf device does not. e) A real emf device has a potential difference across its terminals, but an ideal emf device does not

The answer is option D.

Explanation:

An EMF device is a device that produces an electromagnetic field and the components that it has also have their own internal resistance.

This is the case in a real life EMF device but for an ideal EMF device, the internal resistance is equal to zero so there is no voltage drop because of that.

The answer is option D.

I hope this answer helps.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

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
