Answer:
Reversal of Earths magnetic field
Explanation:
Earth’s magnetic field reverses direction approximately every 2 million years. Every time Earths magnetic Field reverses, the magnetic direction of new sea floor along mid-ocean ridges also reverses. These alternating layers of magnetized seafloor can be used to map out boundaries of diverting plates.
Answer:
yes
Explanation:
this is simple
the horizontal line is adjacent
the vertical line is opposite
recall that cos x=adj/hyp
adj=hyp(cos x)
while opp=hyp(sin x)
Answer:
The escape speed of the planet is 41.29 m/s.
Explanation:
Given that,
Speed = 52.9 m/s
Final speed = 32.3 m/s
We need to calculate the launched with excess kinetic energy
Using formula of kinetic energy
We need to calculate the escape speed of the planet
Using formula of kinetic energy
Hence, The escape speed of the planet is 41.29 m/s.
