While out fishing, Ms. Lacy and Mr. Spencer each catch a fish. When hung
from a vertical spring, Ms. Lacy's fish, which has a mass of 0.988 kg,
stretches the spring by 5.71 cm. Mr. Spencer's fish is then hung from the
vertical spring and dropped from the "no load" position and experiences
SHM with a period of 1.45 s. What is the mass of Mr. Spencer's fish?

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

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.
