${10}^{ - 4} cm$
has on its at a certain time, a total charge of 40 electrons, calculate the energy the would be required to place an addition electron on drop charge on an electron=
$1.6x {10 }^{ - 19} c$
​

Answer 1

Answer:

Mitigation is the effort to reduce loss of life and property by lessening the impact of disasters. In order for mitigation to be effective we need to take action now—before the next disaster—to reduce human and financial consequences later (analyzing risk, reducing risk, and insuring against risk).Steps:

1) Draw a line segment AB of length 9.3 units.

2) Extend the line by 1 unit more such that BC=1 unit .

3) Find the midpoint of AC.

4) Draw a line BD perpendicular to AB and let it intersect the semicircle at point D.

5) Draw an arc DE such that BE=BD.

Therefore, BE=

9.3

units
