Answer:
The potential difference across the source is 30.45 V.
Explanation:
In this setup we have a voltage divider, we were given the voltage difference on one of the resistors, we know that the difference pottential from the source in this case is the sum of the voltage in each individual resistor, so we can use the following equation to solve this problem:
V_resistor5.4 = (V_source)*(R_5.4)/(R_5.4+R_8.3)
V_source = (V_resistor5.4)*(R_5.4+R_8.3)/(R_5.4)
V_source = (12)*(5.4+8.3)/5.4
V_source = (12)*(13.7)/5.4 = 30.45 V
he potential difference across the source is 30.45 V.

Answer:
<em>If the distance doubles, the gravitational force is divided by 4</em>
Explanation:
<u>Newton’s Universal Law of Gravitation
</u>
Objects attract each other with a force that is proportional to their masses and inversely proportional to the square of the distance.
Where:
m1 = mass of object 1
m2 = mass of object 2
r = distance between the objects' center of masses
G = gravitational constant: 6.67\cdot 10^{-11}~Nw*m^2/Kg^2
If the distance between the interacting objects doubles to 2r, the new force F' is:
Operating:
Substituting the original value of F:
If the distance doubles, the gravitational force is divided by 4
I think it’s ( Only the arm length should be changed. The mass should remain the same )
The quantities that are equal to total of the individual values within a circuit are: A) The current in a parallel circuit and the voltage in a series circuit
