An engineer is searching for a material to develop a new indestructible" sunglasses frame. what characteristics would the engineer be looking for

The engineer will be looking for Elasticity, which will permit the sunglasses to bend without breaking. Hardness, which is the resistance of the plastic to deformation and as low Brittleness as possible, which is the probability of breaking a material when little stress is applied, because it breaks without much plastic deformation.

so easy. just google the electromagnetic waves and it’ll pop up.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
