If a simple pendulum is shifted from karachi to mount everest, its time period
a) decreases b) increases c) remains constant d) decreases slightly

I am absolutely sure that If a simple pendulum is shifted from Karachi to Mount Everest, its time period A) decreases. It's pretty easy to sort it out because the only thing you should remember is the higher you go, the more period decreases. And that's all! Hope it helps :)

Although this may be the opposite of what you think i will say it anyway. you were brought into this world for a reason and you still have soo much ahead of you. not everybody has an opportunity of living a great life, but it doesn’t give you a reason to end everything. somebody in the world loves you, and imagine what you would do to them if you left forever.
