Pls help me I can’t do this Part A
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.)

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