The equation you need to use is
where Q is the charge in C, I is the current in Amps and T is the time in seconds.
So we have T = 60s
I =
A
let's work out Q
C
this is the total charge passing a point in a minute so divide by the charge of one electron (
) to find the number of electrons passing the point in a minute which equals
Answer:
R/2
Explanation:
The potential at a distance r is given by :
Where
k is electrostatic constant
q is the charge
The potential (relative to infinity) due to a point charge is V at a distance R from this charge. So,
Put all the values,
<h3>So, the distance at which the potential (relative to infinity) is 2V is R/2.</h3>
I included air resistance because the bike is moving kinda fast so it probably matters for your problem
Vocabulary should be, I think:
I. Hypothesis
II. Evidence, data
III. Experiment
What is your question exactly?
Answer: 0.1125A
Explanation:
We need to know the total resistance which will be:
R = R1+R2
where,
R1 = 20 ohm
R2 = 60 ohm
Therefore, R = 20 + 60 = 80 ohm
We should note that from Ohm's law
v = iR
i = v/R
where,
i = 9/80 = 0.1125 A
Therefore, the current that flows out of the battery is 0.1125A
