Answer:
One meaningful advantage of free enterprise is flexibility. In a free enterprise system, workers can change careers and start a new business at any time. Also, individuals can attempt to launch new ventures to capture untapped markets and meet new demands as they arise.
Explanation:
Answer:
equivalence
Explanation:
Recall that this principle is the basis of Albert Einstein's theory of general relativity. According to the German researcher, gravity is not a force that acts independently on each object, but rather a deformation of the same temporal space tissue.
According to the test carried out now by the team of astronomers, these three dead stars in two of their forms, a pulsar or a white dwarf, are perfect candidates to confirm the theory.
The equivalence was already understood centuries ago by Galileo Galilei. In his famous test of the spheres in the Tower of Pisa he demonstrated the existence on Earth. Subsequently, astronaut David Scott did the same on the lunar surface in 1971.
Now, this team has demonstrated it by studying two of the densest objects in the universe. Until today, many believed that the high density of the pulsar made him exempt from complying with the equivalence principle. However, being subjected to the gravitational field of one of the white dwarfs, the closest and least massive, after six years of observations, they have been able to demonstrate that both bodies have the same acceleration. And, if there is a difference, it is less than three parts between one million. That is the conclusion reached by a new test that tested Einstein and corroborated his theories once again.
Answer: The Rocky Mountains
Explanation:
It is the mountain range that divides the west coast of the USA and Canada from the rest of the countries.
Explanation:
This is a product of two expressions that is equal to zero. Note that any xxx value that makes either (x-1)(x−1)left parenthesis, x, minus, 1, right parenthesis or (x+3)(x+3)left parenthesis, x, plus, 3, right parenthesis zero, will make their product zero.

(x−1)
↙
x−1=0
x=1
(x+3)=0
↘
x+3=0
x=−3
Substituting either x=1x=1x, equals, 1 or x=-3x=−3x, equals, minus, 3 into the equation will result in the true statement 0=0, equals, 0, so they are both solutions to the equation.
