Between two objects, what happens to their gravitational Force if one them were to increases is mass by 4 times?

F=
Gm, m2
p2

A. 4x bigger
B. 4x smaller
C. 2x bigger
D. 2x smaller

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

b. a lightning bug, plug of grass, and a worm

this would be about 43%

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
