A seismographic station receives S and P waves from an earthquake, separated in time by 17.8 s. Assume the waves have traveled o
Georgia [21]

Answer:

D = 230.2 Km

Explanation:

let distance between seismograph and focus of quake is D

From time distance formula we  can calculate the time taken by the S wave

T_1 =\frac{D}{4.5}

From time distance formula we  can calculate the time taken by the P wave

T_2 =\frac{D}{6.90}

It is given in equation both waves are seperated from each other by 17.8 sec

so we have

T_1 - T_2 = 17.8sec

Putting both time value to get distance value

\frac{D}{4.5} - \frac{D}{6.90} = 17.8

D = 230.2 Km

Two examples of ways that physicists model the physical world
AVprozaik [17]

Answering the question, three examples of ways that physicists model the physical world include:

  • Diagrams
  • Equations
  • Computer simulations

Computer simulations refer to the reproduction of behavior of a system with the use of a computer to simulate the results of a mathematical model that is linked with the system.

<h2>Further Explanation</h2>

Computer simulations are a tool that is very useful for mathematical modeling in various natural systems in physics.

Physicists write the rule of our universe using equations. Equations are an aspect of one of the models used by physicists to explain a particular situation.

Physicists use a diagram to convey information. It is a symbolic representation of information with the use of visualization techniques. Diagram provides other means for people to better understand information and process its importance.

Physics predictions about the physical world mainly depend on numerical stimulation, mathematics and empirical observations and Physicists models the physical world based on invariances and laws which are built on mathematical models.

The purpose of physics is to explain or describe everything around us. It described virtually everything around us accurately by deploring the law of physics.

However, physics is considered a natural science because it is based on mathematical analysis which is geared towards findings qualitative physical law for the physical world.
