(Science) Isaac Newton’s universal law of gravitation is an expansion of the planetary motion ideas developed by Johannes Kepler. One derivative of Newton’s universal law gives us a useful formula to find tidal forces on Earth caused by either the Sun or Moon. The tidal force depends on the mass m of the Sun or Moon, the radius r of Earth, and the cube of the distance d between Earth and either the Sun or Moon. (The G in the equation is known as the gravitational constant, and it doesn’t change.)

Ftidal= 2Gmr/d3

Based on the equation and your knowledge of the Sun-Earth-Moon system, which celestial body (the Sun or the Moon) has a greater influence on Earth’s tides? Justify your answer.

Explanation:

the first phase of the government’s plan for settlement was building the transcontinental railroad. the railroad provided a way to bring settlers and manufactured goods west and ship their agricultural and mining produce east. the transcontinental railroad was an essential artery for rapid development of the frontier.

the second phase of the government’s plan was a liberal land distribution policy that made it possible for many people to homestead. with these two key elements—transportation and cheap land—the government rapidly achieved its goal of persuading people to move west, settle on farms, and push back the frontier.

the value of the 4 in the hundreds place is 400 while the value of th e 4 in the tens place is 40

400 is way bigger than 40.
