potential, kinetic, elastc energies
Theyre all in constant motion
Answer:
c. from south to north
Explanation:
since we know that:
F = qv×B
where F is the force and in this case is pointed upward
where v is the velocity due east
the field must be due north by the right hand rule
Therefore, near the equator the magnetic field lines of the earth are directed north from south
Answer:


Explanation:
P = 50 N
Q = 30 N
= Angle between the vectors = 
Resultant is given by

Angle of resultant

Magnitude of the resultant is 
Direction of the resultant is
