As the distance from the surface of the Earth increases, the force of gravity A) increases B) decreases C) stays the same D) may increase or decrease depending on the situation In Newton's Law of Universal Gravitation, the relationship between gravitational force and distance between objects is O a) Directly proportional b) Square-root proportional c) Inverse square proportional d) Inversely proportional

Please answer both parts of question C.

Chap and Gravity Conversion of Mass to Energy converted to energy. How many joules (J) of energy are produced? In a nuclear reactor, 0.15 kilogram (kg) of uranium-235 is completely 1. Read and Understand What information are you given? Mass = m = 0.15 kg Speed of light = c = 300,000,000 m/s = 3 × 108 m/s 2. Plan and Solve What unknown are you trying to calculate? The amount of energy produced = E = ? What formula contains the given quantities and the unknown? E = mc2 Replace each variable with its known variable and known value. E = (0.15 kg)(3.00 × 108 m/s)² E = 1.35 x 10¹6 kg-m²/s² = 1.4 x 1016 J 3. Look Back and Check Is your answer reasonable? Yes, the calculated number is quite large compared to the mass, and the units indicate energy. 2. In a nuclear reactor, 0.20 kilogram of uranium-235 and 0.50 kilogram of plutonium-239 are completely converted to energy. How many joules of energy are produced?

thank you for this explanation. however, i don't really see how it answers the question: does it match the reasoning?
