Nick is conducting a controlled experiment to test whether music daisies grow faster. below are the steps to nick's experiment: 1. plant daisies in two separate flowerpots. 2. place flowerpot 1 in a green room with music. 3. place flowerpot 2 in a similar green room without music. 4. give the daisies the same amount of food and water each week. 5. measure the growth of the daisies. 6. draw conclusions based on the data collected. which group is the control group in nick's experiment?

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.
