A "folk" remedy is something you choose to eat, take, or do,
in order to correct some health issue, because your friend,
your grandmother, your religion, your shaman, your astrologer,
or your medicine man says that it's the right thing to do.
It may or may not be effective, and it may or may not even be
safe. What distinguishes it from mainstream medicine is that
its practices are based on hearsay, and have not been subjected
to scientific methods of investigation and evaluation.

Answer:
Explanation:
A physical quantity which can be completely described by the magnitude and direction both are called vector quantities. For example, displacement, velocity, etc.
A physical quantity which can be completely explained by the magnitude only is called scalar quantity. For example, mass, time, etc.
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,
20 ohms in parallel with 16 ohm= 8.89
20x16/20+16. Product over sum
B is the answer, I’m really good at this subject
