Which of the following is an example of Newtons second law of motion? (2 points) Caties skateboard hits a curb and she falls forward onto the grass. A tissue and a rock are dropped from a ladder. The rock exerts a greater force when it hits the ground. A person stands on a chair and pushes down, and the chair pushes upwards on the person. Tires from a bike push against the road, and the road pushes back.

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

Ryan is examining the energy of the particles in a bar of gold. what is ryan most likely studying?

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.
