suppose that recording station N located 200 km north of the epicenter of an earthquake, and recording station S is located 100
andrezito [222]

Answer:

c.The value of T at Recording Station N would be greater than T at Recording Station S.

Explanation:

We can deduce from the information provided that the value of T at recording station N would be greater than T at recording station S.

This problem relates distance with time.

       Speed  = \frac{disance}{time}

                  Distance  = Speed x time

  • Just like any other physical quantity, speed of a substance is directly related to time.
  • The larger the time taken the farther the distance it will cover assuming the velocity is constant.
  • Earthquake waves for example moves at constant speed with a unique velocity in earth materials.
  • The farther the distance, the more time it will take to reach the seismic recording station.
  • Since N is a distance of 200km from the epicenter, it will take a greater time and have a higher reading of T to reach the station.

What system of units is used by only a small number of countries in the world, including the U.S.?
Aleks04 [339]

Answer:

The correct answer is the imperial system.

Explanation:

Only three countries in the world, that is, the United States, Myanmar, and Liberia use the imperial system. These include measurements in the form of inches, ounces, Fahrenheit, and feet. In the imperial system, the distances, height, weight, or area measurements are used eventually that traced back to everyday items or parts of the body.  

In comparison to other metric systems, the units used in the imperial system are not further differentiated easily into parts of hundreds or thousands, and are thus, regarded of less use in comparison to other metric systems by some. The real follower of the imperial system at present in the world is the United States.
