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.}$

If end diastolic volume (EDV) is measured to be 120 ml/beat and the end systolic volume is measured to be 50 ml/beat, the stroke

laiz [17]

Answer:

70 ml/beat.

Explanation:

Stroke volume may be defined as the volume of the blood that are pumped by the left ventricle in one contraction. The blood output can also be determined by knowing the stroke volume.

The stroke volume can be calculated by the formula as follows:

Stroke volume = End diastolic volume - End systolic volume

Here, end diastolic volume = 120 and end systolic volume = 50.

Stroke volume = 120 - 50

Stroke volume = 70 ml/ beat.

Thus, the answer is 70 ml/ beat.
