You catch, tag, and release 50 fish back into a pond. then, you catch 25 more fish, 5 of which are tagged. what is the best estimate of the number of fish in the pond? a. 100 fish b. 250 fish c. 400 fish d. 625 fish

The friction of the water on a boat produces an acceleration of -10. m/s2. if the boat is traveling at 30. m/s and the motor is shut off, how long it take the boat to slow down to 5.0 m/s?

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 not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
