As a 70-kg person stands at the seashore gazing at the tides (which are caused by the Moon),how large is the gravitational force on that person due to the Moon? The mass of the Moon is 7.35 × 10²² kg,the distance to the Moon is 3.82 × 10⁸ m,and G = 6.67 × 10^-11 N ∙ m²/kg².

The gravitational force can be calculated using Newton's law of universal gravitation: F = G * (m1 * m2) / r^2. Substituting the given values: F = (6.67 × 10^-11) * (70 * 7.35 × 10^22) / (3.82 × 10^8)^2, which results in approximately 0.0024 N.
