Explanation:
The inclined plane is studied by mechanics and, to calculate it, we use Newton's Second Law.
Is a block of mass “m” supported by an inclined ramp at an angle? with respect to the horizontal plane. Despise the friction.
Forces acting on the body are: image 1
P: Force weight = P = m.g
Where: g = 9,8 m / s2
m = body mass given in kg.
FN: Normal reaction force to the plane.
When we neglect friction we notice that the body moves downwards. image 2
I know this one...

Answer:
Research is practical and realistic because it is based on the scientific method, which demands that research should be start with an hypothesis, that should be falsifiable (meaning that it can be proven right or wrong), followed by a scientific study in which the hypothesis is tested.
If the hypothesis is proven to be true, it does not mean that is conclusions will hold true for eternity, they could be proven wrong by further studies.
For this reason, research is both practica, because it is based on a practical method: the scientific method, and realistic, because it has a limited scope, and limited, verifiable understanding of reality, and can be proven wrong with other studies.
Answer:
The answer is: Apply hard work and friendly feeling to relationships with southern whites.
Explanation:
In 1895, Booker T. Washington gave a speech that would open the Cotton States and International Exposition in Atlanta, Georgia. In his speech, Washington suggested that African Americans should not agitate for political and social equality, but should instead work hard, earn respect and acquire vocational training in order to participate in the economic development of the South. By doing so, eventually, he stated, African Americans would gain the respect of white society and be granted the rights of full citizenship.
