The conversion factor you use is 100 cm = 1 m.
You can divide 20 by 100 to get the answer.
20 cm/100 cm =.2 m

Answer:
(b)
Explanation:
The voltage always lags the current by 90°, regardless of the frequency.
Answer:
It would be 2.2 if you have to round the five to the one but if your not rounding the number, it'd be 2.1.
Explanation:
They only conduct when they are in solution form, because then their ions become mobile, and the ions conduct electricity.

Answer:
Explanation:
Use the one-dimensional equation:
which says that the final velocity of a falling object is equal to its initial velocity times the acceleration of gravity times the time it takes to fall. We have the final velocity, -14.5 (negative because its direction is down and down is negative), initial velocity is 0 (because it was held still by someone before it was dropped), and acceleration is -9.8 (negative again, because direction is down while acceleration increases). Filling in:
-14.5 = 0 - 9.8t and
-14.5 = -9.8t so
t = 1.5 seconds
