6. What happens to the frequency if you increase your wavelength and keep wave speed
the same?
7. How can you change the amplitude of the waves?
8. What is the relationship between period and frequency?
9. What kind of waves are shown above? Btw is in another answer that I did .
10. If the wavelength of wave B is 0.45m, what is the wave speed?
I uploaded the other paper btw for 9 and 10

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 ât. the resistance of the coil is r, and the total charge is q = iât, 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 âswipedâ 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 âswipedâ through the reader at exactly the right speed? why or why not?
