Answer:
Solving the given formula for v2 gives us:
Step-by-step explanation:
Solving an equation for a particular variable means that the variable has to be isolated on one side of the equation.
Given equation is:
Multiplying both sides by t2-t1
Adding v1 to both sides of the equation
Hence,
Solving the given formula for v2 gives us:
Correct answer: <span>Dot-and-cross-diagram

Dot-and-cross diagrams are used to represent covalent bonds. The shared electron from one atom is shown as a dot, while the shared electron from the other atom is shown as a cross.
When drawing dot-and-cross diagrams for covalent bonds, you only need to show the electrons in the highest occupied energy level, as only these are involved.
