How high above the earth's surface is g reduced to 8.80m/^2?

Explanation:

We use the equation to calculate gravitational acceleration

where  is the universal gravitational constant , is the mass of the earth: , and is the radius from the center of earth.

Clearing for the distance r:

substituting known values

and since the radius of earth from the core to the surface is about , the distance above the surface where g is reduce to  is:

wich in kilometers is:

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
