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 1 ⁄ 8 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 vibrating tuning fork is struck and begins to vibrate as the object used to strike it is placed away from the tuning fork. c. a pipe's length is equal to 1 ⁄ 2 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 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.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
