The gamma-ray emitting technetium-99m (metastable) is widely used for medical diagnostic studies. Several chemical forms are used to image different parts of the body. Technetium is a remarkable corrosion inhibitor for steel, and adding very small amounts can provide excellent protection.
hope that helps you :)
A flow of positive charges gives the same electric current, and has the same effect in a circuit, as an equal flow of negative charges in the opposite direction.
Since current can be the flow of either positive or negative charges, or both, a convention for the direction of current which is independent of the type of charge carriers is needed. The direction of conventional current is defined arbitrarily to be the direction of the flow of positive charges. So the Answer is Electric Circuits
It does not dissolve readily.
Answer: True
Explanation:
Tissues perform functions that are specializations of the normal function of individual cells.
