a_sh-v [17]

Answer:

10

Step-by-step explanation

The earthquake  measures 6.4 on the Richter scale which struck Japan in Jullu 2007 and caused and extensive damage. Earlier that year, a minor earthquake measuring 3.1 in the Richter scale has stroked in parts of Pennsylvania.

Fomular:

The magnitude of an earthquake is M log(I/S)

where I donates the intensity of the earthquake and S be the intensity of the standard earthquake.

Calculation:

Consider that M1 be the magnitude Japanese earthquake and M2 be the magnitude of the Pennsylvania earthquake and L1 be the intensity of the Japanese earthquake and L2 the intensity of the Pennsylvania  earthquake.

Here the magnitude of the Japanese earthquake is M1 = 6.14 and the magnitude of the Pennsylvania is M2 = 3.1

By the use of magnitude of the earthquake fomular M = log I1/S, the intensity of the Japanese earthquake is calculated as follows .

M1 = log I1/S

I1/s = 10

He hypotenuse of a right triangle is three times the length of one of the legs. the length of the other leg is 648‾‾‾‾√648 feet.
pantera1 [17]
Let length of  the hypotenuse = 3x and length of given leg be x feet.

then (3x)^2 = x^2 + 648
8x^2 = 648
x^2 = 81


so x = 9 and 3x = 27

Hypotenuse is 27 feet and the leg equals 9 feet.

The period 7 (in seconds) of a pendulum is given by T = 2pi√( L divided by 32) where L stands for the length (in feet) of the pe
oksano4ka [1.4K]

Answer:

128 feet

Step-by-step explanation:

t = 2\pi \sqrt{\frac{l}{32} }

So now we will substitute the values of T and π into the equation.

12.56 = 2 \times 3.14 \sqrt{ \frac{l}{32} }

12.56 = 6.28 \sqrt{ \frac{l}{32} }

Divide both sides by 6.28

2 =  \sqrt{ \frac{l}{32} }

Square both sides.

4 =  \frac{l}{32}

Multiply both sides by 32

l = 4 \times 32 \\ l = 128 \: feets
