Answer:
M g H = 1/2 M v^2 potential energy = kinetic energy
v^2 = 2 g H = 2 * 9.80 * 6 = 117.6 m/s^2
v = 10.8 m/s
(C)
Answer:
They are deflected as Earth’s magnetic field exerts force on them.
Explanation:
(Not for cheating, Just to help)
As solar wind approaches Earth, what happens to the charged electrons?
They are absorbed as Earth’s magnetic field exerts force on them.
They grow stronger as Earth’s magnetic field exerts force on them.
They grow weaker as Earth’s magnetic field exerts force on them.
They are deflected as Earth’s magnetic field exerts force on them.
In a level cruise on a passenger airliner, flying in a straight line at a steady 550 miles per hour.
Acceleration is zero.
