If a car stops suddenly, you feel "thrown forward." We'd like to understand what happens to the passengers as a car stops. Imagine yourself sitting on a very slippery bench inside a car. This bench has no friction, no seat back, and there's nothing for you to hold on to. A. Draw a picture and identify all of the forces action on you as thecar travels at a perfectly steady speed on level ground.
B. Draw your free-body diagram. Is there a net force on you?
C. Describe what happens to you as the car slowsdown?
D. Suppose now that the bench is not slippery. As the carslows down, you stay on the bench and dont slide off. What force is responsible for you deceleration?
E. In which directin does this froce point?

a. i. applied force

ii. gravitational force

iii. normal force of reaction

b. net force is zero

c. we move forward

d. frictional force

e. opposite dirction of force applied

Explanation:

no simpler subs form complex ones. synthesise = make

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
