Answer:
Explanation:
Length of bar = L
mass of bar = M
mass of each ball = m
Moment of inertia of the bar about its centre perpendicular to its plane is
Moment of inertia of the two small balls about the centre of the bar perpendicular to its plane is
Total moment of inertia of the system about the centre of the bar perpendicular to its plane is
I = I1 + I2
The answer is B,
because it is more round and lower than the other mountains.
The steeper and more pointy and higher a mountain is, the older it is.
Hope this helps!

Answer:
0.13451 m
0.124196 m
0.119997901132 m
Explanation:
= Velocity of the observer
= Velocity of sound source
v = Velocity of sound in air = 343 m/s
Wavelength is given by
The wavelength is 0.13451 m
From Doppler effect we have the formula
The wavelength is 0.124196 m
The wavelength is 0.119997901132 m
So we want to know how does the speed of a shallow water wave varies. If the wavelength is large enough in comparison to the depth of the water, meaning the wavelength is 20 times longer than the depth of water, the speed of a shallow water wave is the square root of gravity times water depth or: v=√(g*d), where v is speed of the wave, g=9.81 m/s^2 and d is water depth.
True
It goes triassic, Jurassic, Cretaceous
