What is the SI (metric) unit of FORCE?
with symbol ( N )
All the best !
Well you never specified what you're asking... however, this might help you learn the concepts of displacements and magnitude.
: The official displacement formula is as follows: s = sf - si. s = displacement; si = initial position; sf = final position
magnitude is the quantitative value of seismic energy. It is a specific value having no relation with distance and direction of the epicentre.
the magnitude of a vector in any dimension. For a 2d vector the formula is [math]|z| = \sqrt{x^2+y^2}[/math], where x and y are the x and y components of the vector respectively.
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
That information describes the plane's speed.
If he had also told them what direction they were flying, then
they would have been able to put the two pieces of information
together, and they would know the plane's velocity.
