Answer:

The variation and distribution of traits in a population depend on genetic and environmental factors. Genetic variation can result from mutations caused by environmental factors or errors in DNA replication, or from chromosomes swapping sections during meiosis.

babunello [35]

Answer:

People were particularly motivated by one of the candidates

Explanation:

The voter turnout in 2008 spiked because people were particularly motivated by Barrack Obama. His running for presidential position represented a <em>"generational change."</em> So, this means that many of the voters, especially the African-Americans ages 18 to 25 years old became interested in registering in order to vote.

Such kind of voter turnout spike is said to have also occurred during the candidacy of John F. Kennedy, where the voter turnout was<em> 62.8 percent.</em> This was because Kennedy was a <em>charismatic leader</em> who also represented a <u>generational change</u>.

So, this explains the answer.

Determine the magnitude as well as direction of the electric field at point A, shown in the above figure. Given the value of k =
Pavlova-9 [17]

Answer:

The magnitude of the electric field is 8.99*10^{12}N/C in the r direction.

Explanation:

The equation of the electric field is given by:

|\vec{E}|=k\frac{q}{r^{2}}

Where:

  • k is the Coulomb constant is 8.99 *10^{9}\: Nm^{2}C^{-2}
  • q is the charge
  • r is the distance from A to q

|\vec{E}|=8.99*10^{9}\frac{12.5}{0.11^{2}}    

\vec{E}=9.29*10^{12} \vac{r} \: N/C

Therefore, the magnitude of the electric field is 8.99*10^{12}N/C in the r direction.

I hope it helps you!
