Answer:
f_D = =3.24 N/m
Explanation:
data given
properties of air

k = 0.0288 W/m.K
WE KNOW THAT
Reynold's number is given as


= 1.941 *10^4
drag coffecient is given as

solving for f_D


Drag coffecient for smooth circular cylinder is 1.1
therefore Drag force is

f_D = =3.24 N/m
The most important function of a landfill is to store and get rid of solid waste which it provides an area where waste is disposed of and can be managed properly in order to reduce health and environmental risk<span />
Thinking the small glass bead as a single point charge, the electric field generated by it is given by

where

is the Coulomb's constant

is the charge of the bead

is the distance at which we calculate the field.
Using these data, we find:
geyser.........................................
Answer: 1.57
Explanation:
This described situation is known as Refraction, a phenomenon in which light bends or changes its direction when passing through a medium with a index of refraction different from the other medium.
In this context, the index of refraction is a number that describes how fast light propagates through a medium or material.
According to Snell’s Law:
(1)
Where:
is the first medium index of refraction (the value we want to know)
is the second medium index of refraction (air)
is the angle of incidence
is the angle of refraction
Now, let's find
from (1):
(2)
Substituting the known values:
Finally:
