A meteor that originally was heading south breaks up into two chunks. One of the chunks moves southwest. The second chunk was not immediately found, but scientists guessed that they should look for an object heading
a. southeast
b. northeast
c. southwest
d. northwest

A southeast

Explanation:Initially, it was a whole single meteor while moving, but in the course of the movement, it splited into two living one to move southwest, then the other will move in an opposite direction which is southeast

southeast ( A )

Explanation:

when an object moving in a defined direction splits into two equal parts they tend to posses similar kinetic energy therefore the movement of one part will be directly opposite to the movement of the other.

A meteor moving south and later breaking up into two chunks will having its broken chunks moving in the southwest and southeast directions since they are directly opposite directions.hence the scientists should be looking for the second chunk of object heading southeast

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

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
