Answer: -
The acceleration due to gravity at height r = a = GM/r²
Rearranging
r² = GM /a
= (6.674 x 10⁻¹¹ x 5.972 x 10²⁴ ) / 5
r = 8.917 x 10⁶ m
r = 8917 Km
Now Radius of earth = 6371 Km
So height = 8917 - 6371 = 2546 Km
Answer:

Explanation:
The BOD is an empirical test to determine the molecular oxygen used during a specified incubation period (usually five days), for the biochemical degradation of organic matter (carbonaceous demand) and the oxygen used to oxidise inorganic matter.

Explanation:
The basis for classifying changes in matter into physical and chemical change is to see if a material is altered after going through a process.
In a physical change only the state of matter is usually altered especially its form or shape.
Chemical change alters a substance by producing new kinds that are totally different from it.
- In a chemical change, new kinds of matter are usually formed.
- Such changes are usually irreversible.
- Change of state is a reversible process.
