Consider a string of length 1.0 meter, fixed at both ends, with mass 100 grams and tension 100 Newtons. Give the number of nodes and antinodes set up on the string if it is driven at a frequency of 95 hertz. Be sure to include the ends of the string ..
Let the x axis be parallel to the ground, +y direction be vertically upward, and take as an origin the point on the ground directly below the top of the ramp.
A standing wave of 625 Hz is produced on a string that is 1.33 m long and fixed on both ends. If the speed of waves on this string is approximately 333 m/s, how many antinodes are there in the standing wave?
A merry go round at a children's playground can be approximated as a uniform circular disc with a diameter of 3.72 m and a mass of 288 kg. A constant force of 178 N is applied perpendicular to the outer edge of the merrygoround. How long does it t..
