Light is an oscillating electric field alone. an oscillating electric field and a fluctuating magnetic field that are parallel to each other. an oscillating electric field and a fluctuating magnetic field that are oriented randomly with respect to each other. an oscillating electric field and a fluctuating magnetic field that are perpendicular to each other. a fluctuating magnetic field alone.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

Glass has a hardness that is in the middle of the hardness scale. what is the hardness of glass?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
