Explanation:
a=5
b=9
c=3
d=4
that's the correct brainliest answer
3+2=5
+ + +
1 +3 =4
= = =
4+5=9
False
Explanation:
This is false because there is no solution and salt bridge to facilitate the movement of electrons from the two metals.
This connection is not an electrochemical cell because other components are absent. To fully form the electochemical cell which allows a potential difference to be set up;
- Presence of electrodes
- Presence of a solution
- Wire
- Salt bridge
Just wires and the electrodes are given in this set up and it will not work.

400 BTU of wasted heat energy is present in the form of electricity.
<h3><u>Energy sources and usage</u></h3>
- Potential energy sources include fossil fuels like coal, oil, and natural gas. Other energy sources include hydro, solar, and wind.
- Additionally, nuclear energy may also come from radioactive materials.But energy will constantly lose its strength.
- Industries would never be able to derive a full amount of energy from their sources.We can only obtain 60% of the energy in ideal situations, such as the Carnot engine. This is if the case is ideal. Actually, we receive considerably less than this for roughly 40%.
So, when efficiency is 60%, energy is used 60% of the time and lost 40% of the time. Thus, according to question, the energy that is wasted is:
1000 BTUx (40/100) = 400 BTU

An electric current can be carried through a metal by the free flow of the shared electrons.
Answer: A butterfly population includes both green and yellow butterflies, and a predator sees yellow more easily than it does green" would lead to evolution since the green ones would live on.
