If the scientist repeats the experiment over and over and gets the same results. Also if the scientist peer reviews the experiment to make sure there is no bias in his or her results.
Yes, therefore the object would then slow down
What happens to end a of the rod when the ball approaches it closely this first time is; It is strongly attracted.
<h3>Electrostatics</h3>
I have attached the image of the rod.
We are told that the ball is much closer to the end of the rod than the length of the rod. Thus, if we point down the rod several times, the distance of approach will experience no electric field and as such the charge on end point A of the rod must be comparable in magnitude to the charge on the ball.
This means that their fields will cancel.
Finally, we can conclude that when a charge is brought close to a conductor, the opposite charges will all navigate to the point that is closest to the charge and as a result, a strong attraction will be created.
This also applies to a strong conducting rod and therefore it is strongly attracted.

Answer:
Option D
Explanation:
Resistors are said to be connected in “Series”, when they are daisy chained together in a single line. Since all the current flowing through the first resistor has no other way to go it must also pass through the second resistor and the third and so on. Then, resistors in series have a Common Current flowing through them as the current that flows through one resistor must also flow through the others as it can only take one path.
Total Resistance = R₁ + R₂ +R₃ +R₄ ohm
Note then that the total or equivalent resistance, R has the same effect on the circuit as the original combination of resistors as it is the algebraic sum of the individual resistances.
Total resistance R = 3 + 3 + 3 +3
= 12 ohm
Answer:
a) Total distance travelled = 1.9km + 8.7km + 3.0km = 13.6km
b) Total displacement = -1.9km + 8.7km-3.0km=+3.8km
Total displacement = 3.8km due west
Explanation:
a) Total distance travelled is a scalar quantity it is not affected by the direction it's only concerned with the magnitude.
Total distance travelled = 1.9km + 8.7km + 3.0km = 13.6km
b) Total displacement is a vector quantity it takes into consideration both magnitude and direction.
Taking west as positive and east as negative.
Total displacement = -1.9km + 8.7km-3.0km = +3.8km
Total displacement = 3.8km due west
