The distance between the earth and the sun is about 2.5x10¹¹m. Express SI prefix in kilometers

2.5x10^8 kilometers

Explanation:

Given that:

Distance between the earth and the sun = 2.5x10¹¹metres

Convert distance in metres to kilometers

Recall that 1000 metres = 1 kilometers

So, 2.5x10¹¹metres = Z kilometers

To get the value of Z, cross multiply

Z km x 1000 m = (2.5x10¹¹metres x 1km)

1000Z = 2.5 x 10^11

Divide both sides by Z

1000Z/1000 = 2.5 x 10^11/1000

Z = 2.5x10^8km

Thus, the distance between the earth and the sun is about 2.5x10^8km

f=gm1m2/d^2 it d

f is force g is gravitaiton constant, m1 is mass of first object, m2 is mass of second object. d is distance between two object

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.
