Our two intrepid relacar drivers are named Pam and Ned. We use these names to make it easy to remember: measurements made by Pam
1 answer:
The velocity of Ned as measured by Pam is the interpretation of v.
Answer: Option D
<u>Explanation:</u>
According to question, we know that this is an issue depending on the logical and translation of the factors. From the measured information taken what is gathered by the two people is communicated and we have given as:
The Ned reference framework : (x, t)
The Pam reference framework :
From the reference framework, we realize that ν is the speed of Pam (the other reference framework) as estimation by Ned.
At that point, is the speed of Ned (from the other arrangement of the reference) as estimation by Pam.

The electrostatic force between two point charges is given by:
where
is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between them
In our problem, charge 1 is
while charge 2 is
and their distance is
r=5.0 cm=0.05 m
So, the electrostatic force between them is
And the negative sign means the force is attractive, because the two charges have opposite sign.

as it is given that it covers a total distance 1 * 10^2 m
total time taken by it = 13.6 s
now the average speed is given as ratio of total distance and total time
so the average speed will be 7.35 m/s
now if it starts from rest and achieve the final speed as 7.35 m/s
now we can use kinematics
so its acceleration will be 3.68 m/s^2
