Answer:
Magnets have two poles, called north and south. The like poles are attracted to unlike poles, but like poles repel each other. For example, the north pole of one magnet is attracted to the south pole of another. ... To make objects move with a magnet attach a piece of metal, or another magnet, to it.
Answer:
1400 m
Explanation:
Given:
v₀ = 175 m/s
v = 105 m/s
t = 10.0 s
Find: Δx
Δx = ½ (v + v₀) t
Δx = ½ (105 m/s + 175 m/s) (10.0 s)
Δx = 1400 m
Answer : Option D) 90°N and 90°S
Explanation : The latitudes which are given in the options are the angle to be measured in the direction of north and south respectively taking equator as the central line.
When it is 90°N and 90°S it means it forms an right angle and faces towards north and south respectively with respect to the equator, so there are high chances of pointing towards the Arctic and Antarctic regions respectively; therefore giving greater probability of finding glaciers.
