Not much changes, but there are some great pressure so some hills may form.
Answer:
25N.s=25kgm/s
Explanation:
The resulting momentum in this case is equal to the impulse created by the force 5N during 5 seconds
ΔP=Force.time=F.t
= 5x5=25kgm/s
20,000,000 kg*m/s
p=mv
10,000,000=m(v/2)
20,000,000=mv
Like poles repel and unlike poles attract. Magnetic poles always occur in pairs of north and south—it is not possible to isolate north and south poles.
