Show that the effective mass of the oscillating system is approximately meff = 256 g. hint: use the temporal angular frequency 5.77 rad/s. how does your effective system mass compare to the mass of the hanging object, m = 200 g?
y=0.11 m
edit: i'm not sure what other information is missing. the equation used for the coordinate system is y(t) = y cos(ω t +φ0 ) = (0.105m)cos 5.77 rad/s t + (−1.30 rad). i know that temporal angular frequency=sqrt(k/msys), but i'm not sure where k comes from or if that's even what is being asked here.

Choose a synonym for the underlined homonym (a word with two or more meanings). i did not expect the boat to rock so much. a. boulder c. astound b. sway d. shock

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?

Astudent creates a model of a closed ecosystem by filling a glass tank half full with water, then adding 10 snails and two small aquatic plants. the next day, all the snails are dead. what is the most likely cause of their death?
