It is the ratio of distance an object moves to the amount of time needed to travel the distance.
Option b.
Answer:
The rotation of Earth on its axis causes electric currents to form a magnetic field which extends around the plane
Explanation:
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents.
A = delta v over delta t delta v is calculated with final velocity less initial velocity so delta v is 14 - 6 that is 8m/s and delta t is calculated with final time less initial time as initial always is 0 then is 1 - 0 that is 1 then a = 8m/s over 1 that is 8 then the acceleration is 8m/s^2 (remember that is squared.)
Mostly when your around carpet or anything related to a carpet because when you do it long enough you will generate static electricity i hope this helps
