Jake boils some water to make a cup of tea.
he uses a 5 kw kettle that takes 2 minutes to boil the water.
a)calculate how much energy jake used, in kwh, to boil the water. show your working.
b)another unit that measures the energy used is the joule. calculate how much energy jake used in joules.

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.
