Hey There!_____________________________________

$\huge\boxed{Option D}$

_____________________________________DATA:

Radius of Mercury = R_m = 2.43x10^6m

Mass of Mercury = $M_m = 3.2x10^{23}m$

Distance Satellite above the surface of the Mercury = d = 265,000m

Gravitational Constant = $G = 6.67x10^{-11} \frac{N.m^2}{kg^2}$

_____________________________________SOLUTION:

Since the Satellite is orbiting around the Planet Mercury, due to the centripetal force, and Centripetal force is the force that acts towards the center of the circle, Whereas The gravitational force also acts towards the center of the circle thus we can say that Centripetal force is equal or same as centripetal force. So,

F_g =F_C

Fg is Given by,

$F_g = \frac{GM_MM_S}{r^2}$

Fc is Given by,

$F_c=\frac{M_SV^2}{r}$

Where,

G is Gravitational Constant

M_e is mass of Planet Mercury

M_S is Mass of Satellite

r(small letter) is the distance between the center of the Planet Mercury and the satellite.

V is velocity of satellite

_____________________________________

Now,

$\frac{GM_MM_S}{r^2} =\frac{M_SV^2}{r}$

$V = \sqrt\frac{GM_M}{r}$

r can also be written as,

$V = \sqrt\frac{GM_M}{R_M +d}$

Substitute the variables,

$V = \sqrt{\frac{(6.67x10^{-11})x(3.2x10^{23})}{2695000}$

Simplify the equation,

V = 2814 $\frac{m}{s}$

Approximately,

V = 2800 $\frac{m}{s}$

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

Answer from: Quest

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
