3. Organ pipes (open at one end only) resonate best at their first resonant length. A pipe has a length of 30.0 cm. a. What is the wavelength of the sound emitted by the pipe? b. What is the resonant frequency of the pipe if the speed of sound is 341 m/s? c. What is the air temperature in this church?

length? 2. A tuning fork vibrating with a frequency of 950 Hz is held near the end of an open air column that has been adjusted to its first resonant length at 25.0 °C. How long is the tube in centimetres?

We will focus on the wavefront closest to the barrier. Draw the incident wave ray indicating the direction of motion of the incident wavefront. Draw this ray from the top end of the wavefront and show the ray in contact with the barrier. Draw a normal (using a dashed line) and label the angle of incidence ( θi ) for this wave ray. Draw the reflected wave ray and label the angle of reflection ( θ r ). Draw one possible location of the reflected wave crest anywhere on the reflected wave ray. In your answer pay particular attention to the orientation of the reflected wavefront relative to the reflected wave ray. Also be careful to indicate what part of the reflected wavefront is connected to the reflected wave ray.

A conductor of length 0.6 m moves at 15 m/s perpendicular to a magnetic field of 1.5 T. Calculate the induced emf.

and q₂), separated by a distance r is: 9192 FE = ke +-2 Where k is the Coulomb constant. Electric Field The electric field, E, at some point in space is defined as: 54 E == where q is a test charge located at that point. From Coulomb's law, the electric field due to a single point charge, Q is: Electric Potential E=kg 07 The electric potential difference (voltage) between two points (V) is related to the potential energy between those points (U) as: U 10 V== Where q is a test charge.
