The concept most consistent with a contemporary definition of wellness is
a. absence of chronic disease.
b. a healthy mind indicates a healthy body.
c. overall well-being.
d. being without unpleasant symptoms.

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m

the gravitational force on an object increase as the mass of an object also, im not going to report you, but this question should be under the science category, not health
