You now put a cap on the bottom of the tube, closing it off and making it water tight. The loudspeaker continues to broadcast at 1372Hz but the tube no longer resonates with this frequency. I orient the tube vertically and slowly pour water into the tube. I listen carefully for the tube to resonate again with the loudspeaker (fixed at 1372Hz) due to standing sound waves in the air above the water inside the tube. How many times will I hear the tube resonate before it is completely full of water

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm). (e

What is the role of the ocular lens?

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
