A distance-time graph shows the motion of two bicycle riders. Each rider's motion is represented on the
graph by a diagonal line sloping upward from left to right. The graph
shows that they traveled the same distance. However, the line representing the motion of Rider #1 slopes upward more steeply than
the line representing the motion of Rider #2. Sketch a graphical model of
the motions of the riders. Develop an argument on which rider arrived at
his or her destination first. How do you know? Use evidence to add
validity to your argument.

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.

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.

Which of the following is a true statement about the acceleration ~a of the pendulum bob ~a is equal to the acceleration due to gravity. ~a is perpendicular to the bob’s trajectory. ~a is equal to the instantaneous rate of change in velocity. ~a is tangent to the bob’s trajectory.
