Answer:
A. body muscles
The pressure needed to pump blood back to the heart is produced by the <u>body </u><u>muscles </u><u>.</u>
The electric field, or any field such as magnetic field or gravitational field, is the strongest the closer we get to the source of the field. The concentration of field lines also increases closer to the object; these field lines are seen to be coming out of a positive charge.
Therefore, the strongest electric field is at the point where the concentration of electric field lines is the highest.
Polymerization
For example:
nCH₂=CH₂ ---p,T,kat.----> -[-CH₂-CH₂-]- n
Answer:
The war of the currents, sometimes called battle of the currents, was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s.
Explanation:
1st find the pOH = 14 - 4.75 = 9.25
then do 10^-9.25 = 5.62x10^-10 OH- concentration
