It is a false statement i.e. drift velocity is not same in the direction as the applied force.
Drift velocity of a current-carrying conductor can be explained as, the charges i.e. electrons do not flow in the same direction of current. In other word, in most cases the movement of the electrons is almost random, with a small net velocity. So that , the drift velocity, in the direction opposite to the electric field.
Drift velocity
is inversely proportional to the number of electron per unit volume of the conductor e. Therefore, the formulation can be given as ,
= σ E/ne
The above equation shows the drift velocity in a current carrying conductor
where,
is drift velocity , σ is the conductivity, E is electric force and n is number of electrons per unit volume of the conductor e.
Hence here we can say that, the drift velocity is not in the same direction as the applied force.

If you use the right hand rule for these problems, you usually make your fingers and thumb sit at right angles to each other. What each of the two fingers means and that related to the thumb is a different story. All you have to understand at this point is that all three are mutually perpendicular.
That makes C the answer.
All the other choices don't make that clear.

This is a straight definition question. The definition says exactly what D says.
The exact distance from the seismic station to the epicenter is 6000 km.
<h3>
Epicenter of earthquake</h3>
The earthquake's epicenter is the point above the fault location on the earth's surface.
Given that:
A p-wave arrives at 3:00:00 and the s-wave arrives at 3:07:20.
Difference in arrival time = 3:07:20 - 3:00:00 = 7 minutes 20 seconds
From the earthquake time travel graph, a time difference of 7 min 20 sec is at x = 6
The exact distance from the seismic station to the epicenter is 6000 km.
