Air, glass, plastic, wood, rubber are good insulators
Quantum mehcaniccs are a multiple way for selection
Correct answer choice is :
B) Chemistry
Explanation:
Advanced titanium-based compounds have been also used for some years for extremely stressed femoral segment stalks. Both metal samples present a higher impedance to pitting, crack, and galvanic corrosion, stress corrosion weakening and corrosion burnout than polished stainless steel of comparatively low power properties. For this purpose, the low element power of hip prostheses made of the recent stuff is paid for by a larger cross-section of the prosthetic stem, this depending on the geometric situations of the femur.

<h3>
What is cation-exchange resin?</h3>
- A resin or polymer that serves as a medium for ion exchange is known as an ion-exchange resin or cation-exchange resin.
- It is an insoluble matrix (or support structure) made from an organic polymer substrate, typically appearing as tiny (0.25-1.43 mm radius) microbeads that are white or yellowish in color.
- The process is known as cation-exchange resin because the beads are often porous, providing a wide surface area on and inside them where the trapping of ions takes place along with the concomitant release of other ions.
- cation-exchange resin comes in many different varieties. Polystyrene sulfonate is the main ingredient in most commercial resins. Many diverse separation, purification, and decontamination techniques use cation-exchange resin.
- The most typical examples are water filtration and water softening.

Answer:
Differences between Orbit and Orbitals
Orbit
An orbit is the simple planar representation of an electron.
It can be simply defined as the path that gets established in a circular motion by revolving the electron around the nucleus
The shape of molecules cannot be explained by an orbit as they are non-directional by nature.
An orbit that is well-defined goes against the Heisenberg principle.
Orbital
An orbital refers to the dimensional motion of an electron around the nucleus in a three-dimensional motion.
An orbital can simply be defined as the space or the region where the electron is likely to be found the most.
The shapes of the molecules can be found out as they are directional by nature.
An ideal orbital agrees with the theory of Heisenberg’s Principles.
