Answer:
When a negative charge is brought near one end of a conductor electrons are repelled. ... When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor. Electrons will move toward the positive side.
I think it would me 5/0.5 = 10mph
The conductors carry current which is required to power appliances and lights. The insulators are around the conductors to keep them from touching each other, from touching the house, or any other thing besides what they are powering. Without insulators, houses would be likely to burn down
So it can be easily absorbed into the blood steam.
Answer:
The magnitude of the change in the momentum of the ball during the rebound is 4.4 kg-m/s.
Explanation:
Given that,
Mass of the ball, m = 0.1 kg
Initial speed of the ball, u = 25 m/s
Final speed of the ball, v = -19 m/s (the ball rebounds so it will be negative)
We need to find the magnitude of the change in the momentum of the ball during the rebound. The change in momentum of the object is equal to the difference of final and initial momentum.



or

So, the magnitude of the change in the momentum of the ball during the rebound is 4.4 kg-m/s. Hence, this is the required solution.
