Answer:

A biosphere

Explanation:

Biosphere refers to the zone of life on a planet. It includes all living elements of a planet. It is also known as Eco-sphere and includes the interaction of all living being with their surrounding.

Of all the planets and exo-planets, Earth is the planet known to have life and thus biosphere.

Whereas atmosphere, lithosphere and cryosphere can be found on other planets as well.

Atmosphere: Layer of air and gases surrounding a planet or any celestial object. (Except Mercury, all the planets of solar system have atmosphere)

Lithosphere: it refers to the rigid outer part of the planet which includes crust and mantle. (All the rocky planets have lithosphere)

Cryosphere: portion of the planets where water is in ice form. (Many exoplanets have been discovered having cryosphere)

Consider two identical insulated metal spheres, A and B. Sphere A initially has a charge of -6.0 units and sphere B initially ha

Oksi-84 [34.3K]

Answer:

<em>-2 units of charge</em>

Explanation:

charge on A = Qa = -6 units

charge on B = Qb = 2 units

if the spheres are brought in contact with each other, the resultant charge will be evenly distributed on the spheres when they are finally separated.

charge on each sphere will be = $\frac{Qa + Qb}{2}$

charge on each sphere = $\frac{-6 + 2}{2}$ = $\frac{-4}{2}$ = <em>-2 units of charge</em>

Find a numerical value for rhoearth, the average density of the earth in kilograms per cubic meter. Use 6378km for the radius of

Radda [10]

According to the information provided to define an average density, it is necessary to use the concepts related to mass calculation based on gravitational constants and radius, as well as the calculation of the volume of a sphere.

By definition we know that the mass of a body in this case of the earth is given as a function of

$M = \frac{gr^2}{G}$
