D. 558 km/h because if you divide 1,395 by 2.5 you’ll get the answer and I know this is correct because the keyword for me to divide is average.
The second one is the answer
Answer: static electricity
Explanation: The movement of charged particles through a wire or other medium is called current or electricity. There is also static electricity, which results from an imbalance or separation of the positive and negative charges on an object. Static electricity is a form of electrical potential energy
Answer:
The speed of the electron is
.
Explanation:
Given:
Mass of electron is, 
Radius of circle is, 
Force acting on the electron is, 
Now, we know that, for a circular turn, the force acting on the electron is due to centripetal force. Centripetal force acting on the electron is given as:

Here, 'v' is the velocity of the electron.
Now, plug in all the given values and solve for 'v'. This gives,

Therefore, the speed of the electron is
.
I believe the answer would be D. environmental push and pull factors and cultural push and pull factors. Hope this helped! :)
