What is the physical quantity that represents the quantity of matter weight mass time length

mass

Explanation:

We see the definitions for each option.

Weight: Weight is the force with which earth attracts a body towards itself. Weight changes with the value of acceleration due to gravity.

Mass: Mass is defined as the quantity of matter contained in a body. It remains constant anywhere in the universe.

Hence, it is clear from the definition that the physical quantity that represents the quantity of matter is:

mass

i think they are all correct

explanation:

they seem good

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
