Answer:
a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
Explanation:
i don't have one
Then the separation between the two pennies will be O.354m.
To find the correct answer, we need to know about the electrostatic force of attraction.
<h3>What is the separation between the pennies?</h3>
- We have given with the information's,
- As we know that the charge of one electron is 1.6×10^-19C.Thus, the total charge on the penny will be,
- We have the expression for electrostatic force of attraction as,
, here given that the electrostatic force equal to the weight of the system.
- We have to find the separation between the pennies.
Thus, we can conclude that the separation between the pennies is 0.354m.

Answer:
Potential Difference = 14 V
Explanation:
We are told that when the capacitor plates are charged to a certain voltage, then we have;
ΔV = 14 volts
Now, the battery is disconnected, so here we have the potential difference between the plates to be given by the formula;
ΔV = Q/C
Now, the charge is conserved on the plates and the capacitance is constant, therefore in this case, the potential difference will remain the same.
Thus;
Potential Difference = 14 V
Answer:
Gravitational potential energy (GPE) = 107.8J
Explanation:
Gravitational potential energy (GPE) = mgh
Where mass(m) = 11kg
Acceleration due to gravity(g) = 9.8m²/s
height = assumed to be 1m
Force(F) = mg
Force(F) = 11×9.8 = 107.8N
Gravitational potential energy (GPE) = 107.8×1
= 107.8J
