Answer:
C. increases
Explanation:
Law of Universal Gravitation
This law establishes that bodies, by simply having mass, experience a force of attraction to other bodies with mass, called gravitational force or gravitational force.
The gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance that separates them.
Formula (1)
where:
G is the universal gravitation constant, G = 6.67 · 10-11 N · m² / kg²
M and m are the masses of the bodies that interact (kg)
r is the distance that separates them. (m)
Problem development
As objects get closer and closer the distance (r) that separates them decreases and because M, m and G remain constant, in formula (1):
, if r decreases then Fg increases.

Answer:
Suzie is 3 blocks north of where she started
Explanation:
Displacement is the minimum distance between the initial and final point of motion.
Here, Suzie first walks 3 blocks north. From there she walks 4 blocks east. Then 2 blocks to the east then 2 blocks north and then 2 blocks east. She covered 4 blocks east toward west. This is the same distance she covered traveling east. But she is 2 blocks north. From there she traveled a block south to the pizzeria and another block to her friends house. She covered the two block she had traveled north.
Hence, Suzie is 3 blocks north of where she started.
