Based on this electric field diagram, which statement best compares the charge of a with b? a. a is negatively charged and b is positively charged. the charge on a is greater than that on b. b. a is negatively charged and b is positively charged. the charge on a is less than that on b. c. a is positively charged and b is negatively charged. the charge on a is greater than that on b. d. a is positively charged and b is negatively charged. the charge on a is less than that on b. e. a is positively charged and b is negatively charged. the charges on a and b are equal.

What conclusion can be made based on the temperature of soil when the light hits the soil at 0°, 45°, and 90° angles in section 2 of the experiment? did your results support your hypothesis? why or why not?

Positive ions differ from neutral atoms in that

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
