Use the travel time function of the interactivity to find the distance between each of your cities (their respective seismometers) and the epicenter of the earthquake. compare the s–p values with the distance (km) values. which of the following are correct?

choose one or more:

a. the longer the s- and p-waves travel, the farther apart their wave fronts are in kilometers.

b. the shorter the time interval is between the arrival of the s- and the p-waves, the farther the seismometer is from the epicenter.

c. the smaller the s–p value is, the farther the seismometer is located from the epicenter.

d. the larger the s–p value is, the farther the seismometer is located from the epicenter.

e. the farther the epicenter is, the greater the time difference in the arrival of the p- and s-waves at a seismometer.

Air enters a horizontal, constant-diameter heating duct operating at steady state at 290 k, 1 bar, with a volumetric flow rate of 0.25 m°/s, and exits at 325 k, 0.95 bar. the flow area is 0.04 m2. assuming the ideal gas model with k = 1.4 for the air, determine (a) the velocity at the inlet and exit, each in m/s, and (c) the rate of heat transfer, in kw flow rate, in kg/s, (b) the mass kg 0.3
