Imagine that a tank is filled with water. The height of the liquid column is 7 meters and the area is 1.5square meters (m2
). What's the force of gravity acting on the column of water?
A. 73,500 N
B. 102,900 N
C. 68,600 N
D. 110,700 N

Answers

Answer 1
Answer:

Given:

liquid column is 7 meters and the area is 1.5 square meters (m2)

Required:

force of gravity

solution:

P = F/A where P is pressure, F is force and A is area

Since P = DgH where D is density, g is gravitational acceleration and H is height

DgH = F/A

F = ADgH

Let us assume D for water is 1000kg/m3

F = (1.5m2)(1000kg/m3)(9.8m/s2)(7m)

F = 102,900N
Answer 2
Answer:

your answer is B. 102,900 N

How did locke's and newton's ideas influence enlightenment intellectuals?

Answers

Here is the answer. How Locke's and Newton's ideas influenced Enlightenment intellectuals by arguing that argued that every person was born with a blank mind.  Locke's ideas suggested that people were molded by experiences. On the other hand, Newton believed that the world operated according to natural laws that could be uncovered through systemic investigation. Hope this helps.

The ideas of John Locke and Isaac Newton had a profound influence on Enlightenment intellectuals by shaping their understanding of human nature, society, and the natural world.

Here are some key ways in which Locke's and Newton's ideas influenced Enlightenment thinkers:

1) Empiricism and Tabula Rasa: John Locke's philosophy emphasized empiricism and the concept of the mind as a "tabula rasa" or blank slate. He argued that individuals acquire knowledge through sensory experience and that the mind is not innately filled with ideas.

2) Natural Rights and Social Contract: Locke's ideas on natural rights and the social contract had a significant impact on Enlightenment thinkers. Locke argued that individuals possess certain inherent rights, including life, liberty, and property, which should be protected by a government.

3) Scientific Method and Universal Laws: Isaac Newton's discoveries in physics, particularly his formulation of the laws of motion and universal gravitation, provided a model for the application of reason and the scientific method. Newton's work demonstrated the power of observation, experimentation, and mathematical analysis in understanding the natural world.

4) Enlightenment Optimism and Progress: Both Locke and Newton fostered a sense of optimism and belief in human progress. Locke's emphasis on reason, education, and the perfectibility of individuals influenced Enlightenment thinkers in their pursuit of knowledge and social improvement.

Overall, Locke's emphasis on individual rights, reason, and social contract, combined with Newton's scientific discoveries and methodological rigor, provided Enlightenment intellectuals with a framework for challenging traditional authority, promoting individual freedoms, and pursuing rational explanations for human behavior and societal organization.
