Water is discharged from reservoir into the atmosphere through a pipe 50 m long. There is a sharp entrance to the pipe and the diameter is 150 mm for the first 35 m. The outlet is 9 m below the surface level in the reservoir. The pipe then enlarges suddenly to 300 mm in the diameter for the remainder of its length. Take f = 0.001 for the booth pipes. Considering losses due to friction in booth pipes and sudden enlargement only, calculate the discharge.​

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 describes how a microwave heats food

The brightest star in the night sky in the northern hemisphere is sirius. its distance from earth is estimated to be 8.7 light years. a light year is the distance light travels in one year. light travels at a speed of 3.00 × 108 m/s. calculate the distance from earth to sirius in miles. (1 mi = 5280 ft) g
