Amagnetically soft material is placed in a strong magnetic field. what is the most likely outcome? a-it will become a permanent magnet because the domains will remain aligned. b-it will become a temporary magnet because the domains will remain aligned. c-it will become a permanent magnet because the domains will easily realign. d-it will become a temporary magnet because the domains will easily realign.

D-It will become a temporary magnet because the domains will easily realign.

The correct answer is D.

Explanation:

When the iron is placed in the magnetic field then it will magnetize and behave like a temporary magnet. The domains of the iron will align.

Magnetically soft material: It is an temporary magnet which is made from a material that is magnetized. It creates its own magnetic field. For example, magnetically soft material is an electromagnet. The direction of this material can be changed easily.

In the given problem, a magnetically soft material is placed in a strong magnetic field. The domains of the magnetically soft material are already aligned but when this material is placed in the magnetic field then the domains will easily realign.

Therefore, the magnetically soft material will become a temporary magnet because the domains will easily realign.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
