Answer:

1- Option (A) and (D)

2- Mercalli scale measures earthquake magnitude depending on its size

Explanation:

Earthquake occurs due to the sudden shaking of the earth. During an earthquake, seismic waves are produced, namely P wave and S wave, and this waves propagates through the interior of the earth depending upon its magnitude and intensity, thus<u> travelling below the earth's surface</u>.

Due to this wave propagation<u> the rocks breaks</u> and adjust themselves and the faulting occurs along the weak zones.

<u>According to the Mercalli scale, the earthquake is measured in terms of intensity of the shaking of the ground and the size</u>. If a small area is affected then its magnitude is less but if an earthquake affects a large area then it is a severe one.

Maurinko [17]

This question is not complete.

The complete question is as follows:

One problem for humans living in outer space is that they are apparently weightless. One way around this problem is to design a space station that spins about its center at a constant rate. This creates “artificial gravity” at the outside rim of the station. (a) If the diameter of the space station is 800 m, how many revolutions per minute are needed for the “artificial gravity” acceleration to be 9.80m/s2?

Explanation:

a. Using the expression;

T = 2π√R/g

where R = radius of the space = diameter/2

R = 800/2 = 400m

g= acceleration due to gravity = 9.8m/s^2

1/T = number of revolutions per second

T = 2π√R/g

T = 2 x 3.14 x √400/9.8

T = 6.28 x 6.39 = 40.13

1/T = 1/40.13 = 0.025 x 60 = 1.5 revolution/minute
