Answer:
2452.5 N/m^2
Explanation:
given:
density =500kg/m^3
viscosity = 10 Pa-s
diameter of tube= 2 m
and L be length
since gravity is the only force shear force will balance it
so we can write
mg=
A=
m=
therefore
putting values we get
calculating we get 2452.5 N/m^2
A transverse wave always move perpendicularly from its medium. In the problem the medium is the rope. So when the transverse wave movement is left and right, the perpendicular equivalent movement of the rope is up and down.
Answer:
Cognitive images
Explanation:
Stereotypical images: is a wrong image or belief an individual have about a thing or a person.
Territorial markers: is the marking of a space with odorous substances by animal so as give a no tress pass warning.

Cognitive image refers to as images form in an individual's mind when him/her thinks of certain place due to his/her own knowledge and beliefs about that place. Thus option A is the answer.
Answer:
Explanation:
The speed of light (electromagnetic wave) is given by the following formula:
(1)
Where:
is the speed of light
the frequency
the wavelength
So, we have to find from (1):
(2)
But we are asked to find the wavelength in nm. If we know , then:
Finally:
