<h2>
Answer: 1 to 12.
</h2>
<u>The Mercalli seismological scale is a scale of 12 degrees</u>, where 1 is very weak and 12 catastrophic.
This scale owes its name to the Italian physicist Giuseppe Mercalli and was developed to assess the intensity of earthquakes through the effects and damages caused to different structures.
This means the <u>Mercalli scale measures how strong a earthquake has been by </u><u>its consequences and not by its magnitude</u><u>, therefore it is based on </u><u>empirical observations.</u>
Answer:
5.5 rad/s
Explanation:
The friction between the coin and the turntable provides the centripetal force that keeps the coin in circular motion. Therefore, we can write:
where
is the coefficient of friction
m is the mass of the coin
is the acceleration of gravity
is the angular speed
r is the distance of the coin from the centre of rotation
In this problem,
r = 11.0 cm = 0.11 m
The coin starts to slip when the centripetal force becomes larger than the maximum frictional force:
Solving for , we find the angular speed at which this happens:
Answer:
Bcz it depends on fundamental units
In order to start an essay, you would have to write an introduction, say something that will catch the audiences eyes. Ask a question, have a scenario, add some interesting things. Like a fun fact! Don’t forget to state your prompt in your introduction and you will get finish in no time. Good luck!

Answer:
Mass: the quantity of matter which a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational field.
Example: a person or object may be weightless on the moon because of the lack of gravity, but that same person or object maintains the same mass regardless of location. Knowledge of mass is crucial in science.
