Step 1: 36 km/60 mins = 0.6 km/min
Step 2: 9 km / 0.6 km = 15 mins

The magnitude, M, of an earthquake is defined to be M = log StartFraction I Over S EndFraction, where I is the intensity of the

uranmaximum [27]

The equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is $\rm M = log\left ( \dfrac{10S}{S}\right )$ .

Given

The magnitude, M, of an earthquake is defined to be M = log StartFraction I Over S EndFraction, where I is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and S is the intensity of a "standard" earthquake, which is barely detectable.

<h3>The magnitude of an earthquake</h3>

The magnitude of an earthquake is a measure of the energy it releases.

For an earthquake with 1,000 times more intense than a standard earthquake.

The equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is;

$\rm M =log \dfrac{I}{S}\\\\M = log \dfrac{10s}{s}\\\\M=log 10\\\\M =1$

Hence, the equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is $\rm M = log\left ( \dfrac{10S}{S}\right )$ .

Can someone please help me with this question about given two points?Please help ASAP!!! :(

Answer:

<em>The order of subtraction is not important in any of the coordinates</em>

Step-by-step explanation:

Distance Between Two Points

Given two points (x1,y2) (x2,y2), the distance between them is given by the formula

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The difference between both coordinates is squared, then added, and finally extracted the square root.

Based on the principle that

$a*a=a^2$

and also

$(-a)(-a)=a^2$

We can notice it doesn't matter the sign of a the square of a is always positive. If we had subtracted in the opposite way, the distance would have resulted in exactly the same. In other words, the above formula is exactly the same as

$d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$

As seen, it applies for both coordinates

Which is bigger:<br> 3/8 or 0.38.<br> Can you tell me how to work it out?please!

Usimov [2.4K]

You do 3 x 8 / 100 to work out 3/8 as a decimal. So its 0.24. 0.38 is bigger
