An ultrasound wave (or any other sound wave) is mechanical energy, and can be said to be a mechanical wave. Waves are not elastic. The term elastic may be applied to the medium through which they travel. There are compression and shear forces (among others) that work on the medium, and the medium may present a more or less elastic response.
the elasticity of an element is derived from the charge keeping them together, so yes air is an elastic medium but not a good one.
sound is produced by vibrating a source threw air. +======================= Answer 2: For mechanical waves to traverse we need an elastic medium.
Type your answer here... sound
The potential energy is the product of the force required to compress or stretch the elastic medium, and the distance of travel. If the force is measured in Newtons and the movement in meters, the work done will be in Joules.

Sound. Heat, light, radar & x-rays are electromagnetic.

A sound wave's structure, by definition, is a longitudinal one. More specifically, it is "a longitudinal wave in an elastic medium."
Vibration works when a rigid or elastic body or medium oscillates from a position or state of equilibrium. The oscillations can be either periodic or random.

Blood contain a special type of protein called fibrinogen. It is a fibrous protein and is insoluble in aqueous medium. They are non-crystalline and are elastic in nature.This type of protein helps in blood clotting due to its elastic nature.
You use 1" more than the waist you're sewing for. This allows for a 1" overlap to sew the elastic together securely. Answer two: Per this entry from Threads Magazine online: The length of elastic should be shorter than the waist seam (after seams and darts are sewn). How much shorter depends on the combination of fabric, lining and elastic. On lightweight fabric with lightweight lining, use clear elastic, and pull the elastic gently as you sew it in place. If the fashion fabric is corduroy or cotton twill with a medium lining, use braided elastic, and stretch the elastic more as you sew it in place because heavy or firm fabrics put more pressure on the elastic. http://www.threadsmagazine.com/item/3740/how-to-shop-for-elastic
Sound waves cannot travel through a vacuum because it needs a medium and a vacuum has nothing within it that can act as a medium.
