Abasketball is pressurized to a gauge pressure of pg= 55 kpa when at the surface of a swimming pool. (pam= 101 kpa). the ball is then submerged in the pool of water which has a density = 1000 kg/m". assume the ball does not change in mass, temperature, or volume as it is submerged.
a. calculate the absolute pressure inside the basketball in kpa when it is at the surface.
b. as the ball is submerged the absolute pressure in the ball
c. as the ball is submerged the pressure outside the ball
d. write an equation for the pressure difference ap between the inside and outside of the ball when it is submerged a distance y below the surface of the water.
e. solve the pressure equation for the depth (in meters) at which the pressure difference between the inside and outside of the ball will become zero. at this depth, the pressure inside the basketball is the same as the pressure outside the ball.

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

c) up is the direction the magnetic force is acting on the charge.

a sonic boom is a loud boom that breaks the sound barrier
