User: Which of the following sets of conditions would result in the highest velocity for a sound wave traveling through air? A. A warm and humid day with a wind moving in the same direction as the sound B. A warm and dry day with a wind moving in the opposite direction as the sound C. A cold and dry day with a wind moving in the same direction as the sound D. A cold and humid day with no wind

Weegy: A warm and humid day with a wind moving in the same direction as the sound - sets of conditions would result in the highest velocity for a sound wave traveling through air. [ ]

User: Which one of the following scenarios accurately describes a condition in which resonance can occur? A. 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. B. 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. C. A vibrating tuning fork is struck and begins to vibrate as the object used to strike it is placed away from the tuning fork. D. 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.

Weegy: A vibrating tuning fork is struck and begins to vibrate as the object used to strike it is placed away from the tuning fork describes a condition in which resonance can occur

A 6.7 kg object moves with a velocity of 8 m/s. What's its kinetic energy? A. 167.5 J B. 214.4 J C. 53.6 J D. 26.8 J
Weegy: A 6.7 kg object moves with a velocity of 8 m/s. 214.4 J is its kinetic energy. Solution: K.E. = 1/2 * mv² K.E. = 1/2 * (6.7) * (8)² K.E. = 1/2 * 6.7 * 64 K.E. = 214.4 J (More)
