The rigth answer is 14.7N
The law of gravitation thus makes it possible to calculate a force exerted between two objects. In a terrestrial reference system, we can then calculate the force exerted between the Earth and an object.
The law applied in this case is P = mass x g (gravitational constant = 9.8 N / kg)
if a book weighs 1.5 kg then: P = 1.5 x 9.8 = 14.7N
Answer: An ellipse that is close to being circular.
The walls of veins have the same three layers as the arteries. Although all the layers are present, there is less smooth muscle and connective tissue. This makes the walls of veins thinner than those of arteries, which is related to the fact that blood in the veins has less pressure than in the arteries. Hope this helps. Have a nice day.
The option which is the most likely reason why the Steady State Theory has been rejected by the scientific community is because scientists worldwide do not agree with its results.
The results the scientists got didn't really match with the theory they proposed, so they decided it was invalid as there was no evidence to support it. Even though the theory was quite popular in the 20th century, still it turned out to be inconclusive.
