WHO EVER ANSWERS CORRECT I'LL GIVE BRAINLIEST Why might it be helpful to us to measure gravity fluctuations on Earth? What is the most important type of information it gives us and why do you think it would or would not be useful?

Gravity varies when the Earth rotates and its mass and density differ based on where you are on the planet. Knowing how gravity affects sea level thus aids geodesists in making more precise calculations. The mean sea level would be higher in parts of the earth where gravitational forces are heavier.

Explanation:

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

the answer would be 32*f
