So the result is not biased or affected in some way
Answer:
As the "plates" on each side of ridges in the seafloor are pulled away, lava comes up from the middle, hardens and "records" the current magnetic field.
Explanation:
Average speed is worked out from dividing distance by time.
A=(vf-vi)/t
a=(50-25)/10
a=2.5m/s^2
Answer:
80 Ω.
Explanation:
In this circuit the resistances are in series.The equivalent resistance of a series circuit is equal to the sum of the resistances. Req= 60 + 20 = 80 Ω.
