Tendons are, essentially, elastic cords stretched between two fixed ends; as such, they can support standing waves. these resonances can be undesirable. the achilles tendon connects the heel with a muscle in the calf. a woman has a 20-cm-long tendon with a cross-section area of 110 mm2 . the density of tendon tissue is 1100 kg/m3.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
