Which one of the following scenarios accurately describes a condition in which resonance can occur? a. a column of air has a height equal to 1β8 of the wavelength of the sound waves produced by a tuning fork vibrating over the column of air in an open pipe that's partially immersed in water. b. a person is holding a tuning fork on one end of a football field and another person is holding a separate tuning fork on the opposite end of the field. c. a pipe's length is equal to 1β2 of the wavelength of the sound waves produced by a tuning fork vibrating over one end of the pipe that's open to the air at both ends. d. a vibrating tuning fork is struck and begins to vibrate as the object used to strike it is placed away from the tuning fork.

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
