Answer:
2 m/s
Explanation:
Given that a student walks 4 blocks east, 1 blocks north, 2 block west and then 1 blocks south in an hour.
The total time = 1 hour
The vertical displacement = 1 - 1
Vertical displacement = 0
Horizontal displacement = 4 - 2
Horizontal displacement = 2
Total displacement = sqrt (2^2 - 0^2)
Total Displacement = 2
Average velocity = displacement/time
average velocity = 2 / 1
Average velocity = 2 m/s
Therefore, her average velocity is 2 metres per second.
Answer:
There is an electric potential between the plates which is released as the
capacitor discharges.
Explanation:
In Electrical or Magnetic forces, opposite charges generate a force field.
At New Moon the percent illuminated is 0; at First and Last Quarters it is 50%; and at Full Moon it is 100%<span>. During the crescent phases the percent illuminated is between 0 and </span>50%<span> and during gibbous phases it is between </span>50%<span> and </span>100%<span>.
so it depends on the phase
