Saying the potential difference between two points is one volt means that 1 joule of work is done to move 1 coulombs of charge from one point to another.
Potential difference or voltage can be defined as the work done or work involved to transfer a unit charge of electricity from one point to another.
In other words, potential difference is the electrical force or electrical pressure needed to move a unit charge (about 6 quintillion electrons) from point A to point B. It is measured in volts.
To calculate potential difference we use;
Potential difference = work done / charge

Answer:
After 9 seconds the object reaches ground.
Step-by-step explanation:
We equation of motion given as h = -16t²+128t+144,
We need to find in how many seconds will the object hit the ground,
That is we need to find time when h = 0
0 = -16t²+128t+144
16t²-128t-144= 0
Negative time is not possible, hence after 9 seconds the object reaches ground.
Answer:
B is correct. Electrons are added to the rod.
Explanation:
Because the fur lose electrons to the rode and because positively charged while the rod because negative
In the object that has, the least inertia.
