A rightward force is applied to a 6 kg object to move it across a rough surface at constant velocity. The object encounters 15 N of frictional force. Draw a system schema and FBD for this situation and then determine all forces from your FBD. Please, I honestly don’t understand!

Acertain radio station broadcasts radio waves that have a wavelength of 298cm what is its broadcast frequency?

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.
