The correct answers are A) determined from the amplitude recorded by a single seismometer. C) represents the amount of energy released. D) uses a logarithmic scale.

The news media often report an earthquake's magnitude on the Richter scale. The following items are characteristics of a Richter earthquake magnitude: determined from the amplitude recorded by a single seismometer, represents the amount of energy released, and uses a logarithmic scale.

When measuring the scale of the magnitude of earthquakes, the Richter scale measures the scale od moderated size earthquakes. It was invented by two United States seismologists: Charles F. Richer and Beno Gutenberg. They developed the measure in California when they were researching from 1927 through 1936, in the Seismological Laboratory of the Carnegie Institution of Washington, in Pasadena, California.

1. If a bolt is size 1/2" or larger, then its corresponding wrench size should be____ larger than the bolt size
Mrac [35]

Answer:

  1. C. 1/4"
  2. B. 3/16"

Explanation:

1. For hex bolts, lag bolts, and square bolts, the wrench size is 1/4" larger than the bolt size for 1/2" and 9/16" bolts. For 5/8" bolts and larger, the wrench size is <em>50% larger than the bolt size</em>.

__

2. For 7/16" bolts, the wrench size is 5/8", so is 3/16" larger than the bolt. This holds down to 1/4" bolts, where the wrench size may be 3/8" or 7/16".

You have the assignment of designing color codes for different parts. Three colors are used on each part, but a combination of t
Masja [62]

Answer:

7 available

Explanation:

Since 3 colors are available r = 3

Total combination = 35

nCr = 35 ---1

nCr = n!/(n-r)!r!---2

We put equation 1 and 2 together

n-1)(n-2)(n-3)!/n-3)! = 35x 3!

We cancel out (n-3)!

(n-1)(n-2) = 210

7x6x5 = 210

nC3 = 35

7C3 = 35

So If there are 35 combinations, 7 colors are available.

Thank you!

A heat recovery system​ (HRS) is used to conserve heat from the surroundings and supply it to the Mars Rover. The HRS fluid loop
blagie [28]

Answer:

0.304 L of Freon is needed

Explanation:

Q = mCT

Q is quantity of energy that must be removed = 47 BTU = 47×1055.06 = 49587.82 J

C is specific heat of Freon = 74 J/mol.K = 74 J/mol.K × 1 mol/120 g = 0.617 J/g.K

T is temperature in the area of Mars = 189 K

m = Q/CT = 49587.82/(0.617×189) = 452.23 g = 452.24/1000 = 0.45223 kg

Density of Freon = specific gravity of Freon × density of water = 1.49 × 1000 kg/m^3 = 1490 kg/m^3

Volume of Freon = mass/density = 0.45223/1490 = 0.000304 m^3 = 0.000304×1000 = 0.304 L
