Which statement is not true? objects that are good absorbers of radiation are good reflectors as well. the hottest radiating bodies produce the shortest wavelengths of maximum radiation. hotter objects radiate more total energy per unit area than do colder objects. all objects, at any temperature, emit radiant energy.

Which of the following is not a physical property of mattera. melting pointb.heat of combustionc. viscosityd. boiling point

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.

In addition to gravity, what is the other predominant force that affects the motion of a pendulum?
