Answer:
This is a paradox — an inconsistency that often leads people to think that time travel cannot occur in our universe." A variation is known as the "grandfather paradox" — in which a time traveler kills their own grandfather, in the process preventing the time traveler's birth

If one reverse the orientation of a permanent magnet ITS MAGNETIZATION WILL BE PERMANENTLY REVERSED. This is because, the magnetic domains inside the permanent magnet aligned with the new applied field and increase with it while those domains that are anti aligned with that field will shrink.
Things that rust -metals, pipes , car bodies , bolts
Answer:
c They can only travel without a medium.
Explanation:
Electromagnetic waves are made up of electric field and magnetic field.
Here electric field will induce magnetic field and magnetic field will induce electric field.
So this type of field do not require any medium and in vacuum or air the speed of electromagnetic waves are same as speed of light
also we have different range of electromagnetic waves out of which a small range of electromagnetic waves is of visible region in which these waves are visible to us.
so correct answer is
c They can only travel without a medium.
Answer: t = 1.6s
Explanation: Use Fab 5 equation to solve for t (d is irrelevant so use equation without d)
vi = 16m/s, a = -10m/s^2, vf = 0m/s, t = ?
(Assume up is positive so acceleration is negative!!!)
a = vf - vi / t
-10 = 0 - 16 / t
-10t = -16
t = 1.6s
Hope this helps! :)
