The point on the earth's surface directly above the point where the fault first ruptures is called the ____________.

1 answer:

8 0

This point is called the epicenter. The epicenter is important when it comes to the Earth's surface, because it pinpoints where Earthquakes begin to take shape and occur. It is the place where the most damage is caused by an earthquake and is found above the hypocenter.

Use the equation d=m/v. If a rock has a density of 2g/cm^3 and a volume of 8cm^3, what is the mass?

Ray Of Light [21]

Answer:

The mass is 16 [g]

Explanation:

We have to remember the formula that defines density, which mentions that the density is equal to mass divided by the volume.

$Density = mass / volume\\where:\\density = 2[\frac{g}{cm^{3} } ]\\Volume = 8 [cm^{3}]$

Now we clear the mass:

$mass= density*volume\\mass = 2[\frac{g}{cm^{3} }]*8[cm^{3} ]\\mass = 16 [g]$

The trunk of a elephant may extend up to 2.2 m. It acts much like an organ pipe only open at one end when the elephant blows air

Talja [164]

Answer:

1) f = 38.63 Hz , 2) f = 115.9 Hz

Explanation:

The elephant's trunk can be approximated by a tube with a closed end, in pipes the closed ends correspond to nodes and the open ends to antinodes or bellies.

The expression for the wavelengths of this system is

4L = n λ

n = 1, 3, 5, 7 ...

also let's use the relationship between frequency and wavelength and wave speed

v = λ f

f = v / λ

f = v n / 4L

f = v / 4L n

1) the fundamental frequency occurs for n = 1

f = 340/4 2.2 1

f = 38.63 Hz

2) The first harmonic

n = 3

f = 340/4 2.2 3

f = 115.9 Hz
