A negative test charge experiences a force to the right as a result of an electric field. Which is the best conclusion to draw
zaharov [31]

Answer:

The electric field points to the left because the force on a negative charge is opposite to the direction of the field.

Explanation:

In an electric field, a positive charge has tendency to move from high to low potential and hence experience the electric force in the direction of electric field since electric field lines are directed from high to low potential.

In an electric field, a negative charge has tendency to move from low to high potential and hence experience the electric force in the direction opposite to  electric field since electric field lines are directed from high to low potential.This phenomenon happened because The electric field from a positive charge will points away from the charge while the electric field from a negative charge will points toward the charge.

Consider an electromagnetic wave where the electric field of an electromagnetic wave is oscillating along the z-axis and the mag
aalyn [17]

Answer:

<em>The wave will be travelling in the y-axis</em>

Explanation:

An e-m wave has a spatially varying electric field that is always associated with a magnetic field that changes over time and vice versa. The electric field and the magnetic field oscillates perpendicularly to each other, and together form a wave that travels in a perpendicular direction to the magnetic and the electric field in space. The movement of the e-m wave through space is usually away from the source where it is generated. So, if the electric field travels in the z-axis, and the magnetic field travels through along the x-axis, then the e-m wave generated will travel in the y-axis direction.

What is the difference between rutherford's model of the atom and bohr's model of the atom
Amanda [17]

Answer:

Rutherford described the atom as consisting of a tiny positive mass surrounded by a cloud of negative electrons. Bohr thought that electrons orbited the nucleus in quantised orbits. Bohr built upon Rutherford's model of the atom. ... So it was not possible for electrons to occupy just any energy level.
