The direction of deflection of an electron beam in a magnetic field can be determined by which of the following?
amid [387]

Answer:

Right Hand Rule

Explanation:

When a charged particle travels in a magnetic field, it experiences a force whose magnitude is given by:

F=qvBsin\theta

where

q is the charge of the particle

v is the velocity

B is the magnetic field strength

\theta is the angle between the directions of v and B

The direction of the force can be determined by using the Right Hand Rule, as follows:

- index finger: this should be put in the direction of the velocity

- middle finger: this should be put in the direction of the magnetic field

- thumb: this will give the direction of the force -> however, for a negative charge (as the electron) the direction must be reversed, so it will be opposite.

Speciation is how new organisms arise. The fossil record's name is self-explanatory: a record of the fossil found. Natural selection is when traits that are better for survival are passed down to the next generation. Therefore, C) radiometric dating is the answer.
