Jake uses a fire extinguisher to put out a small fire. when he squeezes the handle, the flame rettardant is released from the extinguisher with considerable force. as a result, jake has to reinforce his grip on the extinguisher to hold it in place as it pushes back into his hands. the projectile in this scenario is the . the recoil in this scenario is the . the force on the flame rettardant is the force on the extinguisher. the mass of the flame rettardant is the mass of the extinguisher. the acceleration of the flame rettardant is the acceleration of the extinguisher.

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

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.
