Answer:
B. Electrons are transferred from the fur to the plastic rod.
Explanation:
Triboelectricity or friction charging refers to the ability of materials to gain or lose electrons as a result of rubbing them against something. This phenomenon has been observed in the case of rubbing plastic rod against fur, or glass rod against silk.
In the context of rubbing plastic rod against fur, what happens is that the fur which has an excess of charges loses electrons to the plastic rod. This makes the plastic rod to become positively charged, and the fur, negatively charged.
Use the formula
Time = (distance) / (speed)
-- notice that the distance is given in km. Remember this when you write the speed. They should BOTH be in km it BOTH in meters.
-- for the speed, don't get distracted by the idea of 'music'. It's being sent to us by radio, so use the speed given for light/radio.
A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.
A rectifier is a device that converts an Alternating Current (AC) into a Direct Current (DC) by using one or more contact diodes. ... In simple words, a diode allows current in just one direction. This unique property of the diode allows it to act sort of a rectifier by converting an alternating current to a DC source
I apologise if this is confusing, if it doesn’t make sense just comment and I’ll try to explain it better. :)
Let’s seperate the four directions into two categories: north + south, and east + west.
John’s movements in regards to a north/south direction over the course of the entire placement:
8 north, 8 south (6 + 2 steps = 8 steps south)
In total, John moved both north and south 8 times each.
8 - 8 = 0, therefore canceling out any north/south movement. At this stage, John has not moved from his starting position.
John’s movement in regards to east/west:
6 west, 3 east.
Since he has not moved an equal amount of steps west and east means he HAS moved from his starting point.
In order to find John’s displacement, we must take his east steps from his west steps.
6 - 3 = 3
This means John’s displacement from his starting point is 3 steps west.
