Imagine you have a can with a radius of 10 cm and a height of 20 cm filled to its brim with water. A distance of 8 cm from the bottom of the can there is a small hole with a radius of 0.2 mm in the side of the can.
Calculate the velocity of the water coming out of the hole.
Hints:
1. Write down Bernoulli's equation to relate the water at the top of the can to the water coming out of the hole.
2. Note that the top of the can, the water is in direct contact with the air. So the pressure there is also Р0.

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.
