In digital electronics, the input of an AND gate will be either logic state 1 or 0. If DC Positive logic is
used for the logic states, what voltage would you
expect to read on an input that is logic state 1 in a
5 VDC system?

A) 0 VDC
B) +5 VDC
C) -5 VDC

D) 10 VDC

Two friends are having a conversation. anna says a satellite in orbit is in freefall because the satellite keeps falling toward earth. tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/2 . who do you agree with and why?

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.

Match each type of lever with the correct diagram. 1. first-class 2. third-class 3. second-class
