Athin, 74.0-cm wire has a mass of 16.6 g . one end is tied to a nail, and the other end is attached to a screw that can be adjusted to vary the tension in the wire. to what tension (in newtons) must you adjust the screw so that a transverse wave of wavelength 3.36 cm makes 626 vibrations per second?

What happens to light waves from a star as the star moves away from earth?

The average density of the planet uranus is 1.27 103 kg/m3. the ratio of the mass of neptune to that of uranus is 1.19. the ratio of the radius of neptune to that of uranus is 0.969. find the average density of neptune.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
