"A magnet with a red end and blue end is tied to a string and suspended from the ceiling. The red end is found to orient northward. A second magnet with a green end and yellow end is brought near the first magnet and it is observed that the green end attacts the red end. You then know that the yellow end is a magnetic

A. Northpole
B. Southpole
C. can't be sure because the orientaion of the second magnet in the earth's field not specified.

If we consider the north pole of the earth as the north pole of the magnet in the nucleus of the earth, we have to consider that the the magnet with the red end is a magnetic southpole (because opposite poles try to get closer). Consequently, the green end is magnetic northpole and the yellow end is a magnetic southpole.

Hence, the answer  is

B. Southpole

I hope this is useful for you,

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:
