How do seismologists measure earthquakes?

Chemistry
1 answer:
choli [55]2 years ago
5 0

Answer:

A. By the circumference of the epicenter

Explanation:

If the Earth's lithospheric plates begin to move slowly, stresses emanate in the crust, most at times close to the plate boundaries. These stresses (compression, tension strain, and shear) accumulate in the crust until they surpass the rock's strength or the pressure around an internal fault. And there's a sudden slippage of rock around a fault.

The planet shakes and the rocks lurch to their new position in a matter of seconds as the stress energy is released. Seismic waves move away from the broken portion of the fault, just like ripples from a pebble landing on calm water.

Seismologists may estimate when the slippage started on a fault, the area of the slipping fault, the sum of slippage or fault throw (i.e. just how much the crust moved), and the length of time it takes for the slippage to happen by measuring the circumference of the epicenter which is the mapped area where the earthquake is taken place.

what is the ratio of the rate of effusion of helium (atomic mass 4.00 amu) to that of oxygen gas (molecular mass 32.0 amu)?
nignag [31]

Answer:

3 : 1

Explanation:

Let the rate of He be R1

Molar Mass of He (M1) = 4g/mol

Let the rate of O2 be R2

Molar Mass of O2 (M2) = 32g/mol

Recall:

R1/R2 = √(M2/M1)

R1/R2 = √(32/4)

R1/R2 = √8

R1/R2 = 3

The ratio of rate of effusion of Helium to oxygen is 3 : 1

How does a sample of hydrogen at 10 °C compare to a sample of hydrogen at 350 K?
Aleks04 [339]

Answer: -

The hydrogen at 10 °C has slower-moving molecules than the sample at 350 K.

Explanation: -

Temperature of the hydrogen gas first sample = 10 °C.

Temperature in kelvin scale of the first sample = 10 + 273 = 283 K

For the second sample, the temperature is 350 K.

Thus we see the second sample of the hydrogen gas more temperature than the first sample.

We know from the kinetic theory of gases that

The kinetic energy of gas molecules increases with the increase in temperature of the gas. The speed of the movement of gas molecules also increase with the increase in kinetic energy.

So higher the temperature of a gas, more is the kinetic energy and more is the movement speed of the gas molecules.

Thus the hydrogen at 10 °C has slower-moving molecules than the sample at 350 K.
