Fossil B is older the lower they found the fossil the older it is
In an arithmetic progression, consecutive terms differ by the same value.
So, we have

which reflects the fact that the difference between P and 6 must be the same than the one between P and 14.
The equation solves to

And in fact, if you start with

every pair of consecutive terms differ by 4.
Answer: i can see properly
Explanation:
Answer:
E=12.2V/m
Explanation:
To solve this problem we must address the concepts of drift velocity. A drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field.
The equation is given by,

Where,
V= Drift Velocity
I= Flow of current
n= number of electrons
q = charge of electron
A = cross-section area.
For this problem we know that there is a rate of 1.8*10^{18} electrons per second, that is



Mobility
We can find the drift velocity replacing,


The electric field is given by,
