A flute is essentially a tube that is open at both ends. Sketch the wave patterns associated with the first and third harmonic of a flute that is 67.5 cm long. What frequencies would these waves have if the flute was played at 21.0oC?

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.

How will the system respond to a temperature increase?

Which of the following are guidelines to follow for obtaining accurate observations
