I believe it is Gravitational force, hope this helps
Produced the model is the resistance of the circuits decreased as a battery voltage increased (option-B).
<h3>What connection does there exist between voltage and current, current and resistance, and voltage and resistance?</h3>
Ohm's Law describes how current, voltage, and resistance are related to one another. According to this, as long as the temperature doesn't change, the current flowing through a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
The more work a certain quantity of electrons can accomplish at a given voltage. The quantity of electrons that are presently moving through any one point in a circuit at any particular time is known as the current. At the same voltage, a larger current can perform more work. Current times voltage equals power.

A control is B, standard for comparison. This is used to compare for example plants and using different fertilizers and then have one with no fertilizer. Controls are basically just a base to the entire experiment
I hope this helps you!:)
Answer:
8.01 (10^-10) m
Explanation:
use the Particle in a box equation
E = (n^2) (h^2) / (8 m (L^2))
and energy of a particle as its wavelength equation
h c / lamda = E
combine the equations to get
h c / lamda = (n^2) (h^2) / (8 m (L^2))
get L alone
L^2 = (2^2 - 1^2) h lamda / 8 m c
the longest wavelength is produced by a jump from the first excited state to the ground so
n = 2 to n = 1
so
L^2 = (n1^2 - n2^2) h lamda / (8 m c)
h = 6.6(10^-34) J*s
c = 3(10^8) m/s
m = 9(10^-31) kg
lamda = 700(10^-9) m
n1 =2
n2=1
