South
Explanation:
The magnetic force F on a point charge moving with a velocity v in the presence of a magnetic field B is given by
and according to the right-hand rule, an upward magnetic force on a proton moving westward is only possible if the magnetic field is directed southward.
Answer:
The woman's average velocity during the trip is 36.2 miles/hour.
Explanation:
Velocity can be define as the displacement of an object per time. It is a vector quantity, and measured in m/s.
i.e velocity =
From the given question,
Displacement =
=
=
= 425
The displacement of woman is 425 miles.
velocity =
= 36.1702 miles/hour
The woman's average velocity during the trip is 36.2 miles/hour.
