The statement which is true is as follows:

  • As evidence changes, scientific theories can also change.

Thus, the correct option is A.

<h3>What is Scientific theory?</h3>

A Scientific theory may be characterized as a well-determined description of some features of the natural world, based on a body of certainty that has been repeatedly assured through observation and experiment.

Scientific theories describe the natural world, while scientific law explains natural phenomena. It is not assumed that if a single study or inference is wrong, a scientific theory can be invalidated. It undergoes a series of protocols before rejection.

As evidence is modified or changed, the scientific theories can also be altered on the basis of it.

Therefore, the correct option for is question is A.

The first P-wave of an earthquake took 11 minutes to travel to a seismic station from the epicenter of the earthquake. What is t
iris [78.8K]

Answer:

\large \boxed{\text{5280 km; 25.5 min }}

Explanation:

1. Distance from epicentre

The average speed of P-waves is about 8 km/s.

(a) Convert minutes to seconds

\text{Time} = \text{11 min} \times \dfrac{\text{60 s}}{\text{1 min}} = \text{660 s}

(b) Calculate the distance

\text{Distance} = \text{ speed} \times \text{time} = \dfrac{\text{8 km}}{\text{1 s}} \times \text{660 s} = \textbf{5280 km}\\\\\text{The seismic station's distance to the epicentre is $\large \boxed{\textbf{5280 km}}$}

2. Time for S-wave

The average speed for an S-wave is about 3.45 km/s.

\begin{array}{rcl}\text{Distance} & = & \text{speed} \times \text{time}\\\text{5280 km} & = & \dfrac{\text{3.45 km}}{\text{1 s}} \times \text{time}\\\\5280 \times \text{1 s} & = & 3.45 \times \text{time}\\\text{Time} & = & \dfrac{\text{5280 s}}{3.45}\\\\ & = & \text{1530 s}\\& = & \textbf{25.5 min}\\\end{array}\\\text{It took the first S-wave $\large \boxed{\textbf{25.5 min}}$ to arrive.}
