The ion of idodine is neutral
Surveys are considered the most reliable way to gather data
The time taken for the tiny saliva to travel is 0.55 second.
The horizontal distance traveled at speed of 4 m/s is 2.2 m.
The horizontal distance traveled at speed of 20 m/s is 11 m.
<h3>
Time of motion of the tiny saliva</h3>
The time taken for the tiny saliva to travel is calculated as follows;
h = vt + ¹/₂gt²
where;
- v is initial vertical velocity = 0
- g is the acceleration due to gravity
h = 0 + ¹/₂gt²
h = ¹/₂gt²
2h = gt²
t² = 2h/g
t = √(2h/g)
Substitute the given parameters and solve for time of motion;
t = √(2 x 1.5 / 10)
t = 0.55 second
<h3>Horizontal distance traveled at speed of 4 m/s</h3>
X = Vx(t)
X = (4 m/s)(0.55)
X = 2.2 m
<h3>Horizontal distance traveled at speed of 20 m/s</h3>
X = (20)(0.55)
X = 11 m

The reasoning that can be used to agree with the claim that has ben made is that the human powered generators are the best due to the fact that they would not have to require the long time and they would not have to consume resources.
<h3>What is a claim?</h3>
This is the term that is used to refer to a statement or an assertion that has been made which has not yet been proven.
The human powered generators are the best due to the fact that they would not require the resources that are known to be more consuming. That is they are renewable and like fossils they would not have any forms of adverse effects on the environment that they are used.

<u>Explanation</u>:
Resistivity of silver wire =
Resistivity of copper wire = 
Resistance = Resistivity *length/cross sectional area
So,
For E calculation
For copper
E = resistivity * current density
E = Resistivity * current/area
For silver
Potential difference 
For silver
Potential difference = 
For copper
Potential difference =
