In an electrochemical cell, electrons flow from anode to cathode while current flows in the opposite direction.
<h3>What is an electrochemical cell?</h3>
The question is incomplete but it clearly relates to an electrochemical cell so I will answer in a general way. An electrochemical cell consists of a cathode and an anode. The anode is positively charged while the cathode is negatively charged.
We should note that electrons flow from anode to cathode but the flow of current is in the opposite direction. This occurs because the electron is negatively charged.

Answer:
an ion
Explanation:
- When an atom gains/loses an electron, the atom becomes charged, and is called an ion.
- Gaining an electron results in a negative charge, so the atom is an anion.
- Losing an electron results in a positive charge, so the atom ion is a cation.

Area of circle is 76.44 square units.
We are given that
Base of one sector = b = 1.95 units
Height of sector = h = 4.9 units
Total number of sectors = 16
Area of one sector is equal to area of triangle (approximately)
Area of sector =
Using the formula
Area of one sector=
= 4.7775 square units
Area of circle A = 16 × Area of sector
Area of circle A = 16 × 4.7775
= 76.44 square units
Hence, Area of circle is 76.44 square units.
Option D is true.
