Answer:
w2=5.1736x10^-6m
Explanation:
The relation between the wavelength and width is:
sin(Ф)=m*λ/w
Since the mass and the angle is the same in both cases so:
sin(Ф)=m*λ1/w1
sin(Ф)=m*λ2/w2
The mass and the sinФ are factor in both elements so:
λ2/w2=λ1/w1
w2=w1*λ2/λ1
w2=4.1x10^-6m*665x10^-9m/527x10^-9m
w2=5.1736x10^-6m
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
convergent and counterclockwise
hope it helps :)
A.
nucleus hold protons and neutrons that contain the mass. but is smaller due to the electron cloud making the atom bigger.
