A. This scale measures seismic waves based on their size.
B. This scale rates an earthquake according to how much damage it causes.
C.This scale produces a single rating for earthquakes that reach the surface.
D. This scale uses Roman numerals to rank the damage caused by an earthquake.
E.This scale measures the magnitude of an earthquake based on the size of seismic waves.
<h3><u>
Answer:</u></h3>
The Mercalli scale : This scale rates an earthquake according to how much damage it causes and This scale uses Roman numerals to rank the damage caused by an earthquake.
<h3><u>
Explanation:</u></h3>
The Modified Mercalli scale is intended to illustrate the consequences of an earthquake, at a contracted station, on tangible characteristics, on modern fittings and human beings.
The Modified Mercalli Intensity value ascribed to a particular site subsequent an earthquake has an extra significant means of severity to the nonscientist than the magnitude because intensity assigns to the outcomes really encountered at that position. This scale is comprised of 12 growing levels of intensity, denoted by Roman numerals, arranging from gradual shaking to catastrophic impairment.
Answer:
1/5 or .2
Explanation:
you put miles over seconds 3/15 then simplify to 1/5 to get miles per second
The result of
changing a physical sound wave into an analogous electrical signal using a
transducer (such as a microphone) is called analogue audio. In this system, the rapid electrical level is
directly proportional to the rapid air pressure taken by the transducer. The analogue
signal is then augmented and can be kept on an analogue medium such as tape or transformed
further into a succession of discrete mathematical numbers. The advantages of
using this device is that it yields a subtle sound and is pleasing to the ear
by pushing the signal level and overdriving it. But the disadvantages are
editing it would be tedious and prone to degradation.
Answer:
50J
Explanation:
Potential energy = mass (kg) * gravitational accelerations (10N on earth) * height
250 g in kg = 0.25
0.25 * 10 * 20 = 50 J
