Answer:
<h2>It makes the current viable enough to pass through an exterior wire.</h2>
Explanation:
Electrochemical cells primarily comprise of two half-cells. These half-cells assist in isolating the oxidation and reduction half-reactions. These two reactions are linked by a wire which allows the current to move from one edge to the other. The oxidation at the anode and the reduction take place at the cathode and the addition of a salt bridge helps in completing the circuit and permits the current to flow and leads to the generation of electricity.
Answer:
From the Online Catalog to the Shelf
Libraries in the United States generally use either the Library of Congress Classification System (LC) or the Dewey Decimal Classification System to organize their books. Most academic libraries use LC, and most public libraries and K-12 school libraries use Dewey.
Explanation:
Answer:
No bcz it is insulator it will not conduct electric
Answer:
B) In the field study, it is much harder to control variables than in an experiment
Explanation:
Field study and laboratory experiments are both employed by scientists in discovering answers to investigations. However, while field studies are conducted in a natural or real world scenario, experiments are carried out in the confines of a laboratory.
One major difference between an experiment and field study is that IT IS DIFFICULT TO CONTROL VARIABLES IN A FIELD STUDY THAN IN AN EXPERIMENT. Experimental Research usually occurs under strict controlled conditions where only one variable is being tested at a time and the other controlled. However, in a field study, it becomes difficult to have only one variable being tested as several variables come to play.
