A 0.1 kg mouse is running along a countertop. the mouse has a 1 J of gravitational potential energy. A 5kg cat is sitting on top of a cabinet, stalking the mouse. The cat has 100 J of gravitational potential energy. A 10kg dog is on the floor barking at the cat. The dog has 0 J of gravitational potential energy. The acceleration due to gravity (g) is 10m/s^2 Order the animals from most height to least be sure to use evidence from the first paragraph to justify the answer

Search coils and credit cards. one practical way to measure magnetic field strength uses a small, closely wound coil called a search coil. the coil is initially held with its plane perpendicular to a magnetic field. the coil is then either quickly rotated a quarter-turn about a diameter or quickly pulled out of the field. (a) derive the equation relating the total charge q that flows through a search coil to the magnetic-field magnitude b. the search coil has n turns, each with area a, and the flux through the coil is decreased from its initial maximum value to zero in a time ∆t. the resistance of the coil is r, and the total charge is q = i∆t, where i is the average current induced by the change in flux. (b) in a credit card reader, the magnetic strip on the back of a credit card is rapidly “swiped” past a coil within the reader. explain, using the same ideas that underlie the operation of a search coil, how the reader can decode the information stored in the pattern of magnetization on the strip. (c) is it necessary that the credit card be “swiped” through the reader at exactly the right speed? why or why not?

A100 kg running back runs at 5m/s into a stationary linebacker. it takes 0.5 for the running back to be completely stopped

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
