Alfred Wegener discovered Pangea and the theory that over time they moved apart using tectonic plates.
Answer:
The correct statements are D and E.
Explanation:
The fringe width is given by the following formula as :
Here,
is wavelength of light
D is distance between slit and the screen
d is slit width.
If the between these slits is decreased, the fringe width increases. As a result, the distance between the minima increases and also the distance between the maxima increases.
It is called the atmosphere
If you are talking about sound frequency you need to consider what area you are in because in a concert hall it is big and helps the sound spread but in an airplane it is the opposite.
The pressure value is given by the equation,
Where,
represents the density of the liquid
g= gravity
h= Heigth
A) For the measurement of the guage pressure we have the data data,
Replacing we get,
P_g = 12395Pa[/tex]
In order to find the Absolute pressure, we perform a sum between the atmospheric pressure and that of the Gauge,
B) The atmospheric pressure at sea level is 101325Pa, assuming ideal conditions, we will take this pressure for our calculation, so
