7 0

Answer:

the magnitude of gravitational force would be 20 N

Explanation:

therefore on a body of mass m by earth is \frac{GMm}{r^{2}}

where M  is the mass of earth m is the mass of body, G is the gravitational constant and r is the distance of seperation from centre of earth.

therefore F =m\times \frac{GM}{r^{2}}=mg=10m

therefore F = 20 N.

1.Which statement best describes scientific laws
gtnhenbr [62]
In a way, all of the answers could be argued for (for example: in the first option: if the scientists' opinions are understood to be "informed understanding of the causes of events"), but one of the options is the best:
Scientific laws describe specific relationships in nature without offering
an explanation.

The reason why  I think this is true is that many laws are phased too short and too concise to provide comprehensive explanations, instead they describe the relationships that must hold.


One of the options is pplain false:
Scientific laws explain why natural events occur. -"Scientific laws were theories that have been tested, proven, and adopted as laws." - since they are not adopted as laws.
