the gravitational strength on earth is less than the gravitational strength on neptune. which statement is correct?
a. the mass of an object will be greater on earth than neptune.
b. the mass of an object will be greater on neptune than earth.
c. the weight of an object will be greater on earth than neptune.
d. the weight of an object will be greater on neptune than earth.

The correct answer is D.

Explanation:

The mass of an object can never be changed While the weight of an object can be changed because weight is the product of mass and gravitational acceleration or strength.

                                  w = mg

Value of gravitational strength is different at different places. Greater the Value of gravitational strength, greater will be the weight of the object. As gravitational strength of Neptune is Greater than that of the Earth, So the weight of an object will be greater on Neptune than Earth

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.

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
