1.) A popular way to measure the distance to lightning is to start counting, one count per second as soon as you see the flash. Stop counting when you hear the thunder and divide by five to get the distance in miles (this means that 5 seconds corresponds to a distance of 1 mile). Use this information to estimate the speed of sound in m/s. Distance We know from lecture that: Velocity = %3D Time and in the case of the lighting/thunder example that: Distance = 1ime 5. Combining these two equations we get a value for the speed of sound: Time 3-,milese = 0.2 miles Velocity = %3D %3D Time second 7second Use the conversion of 1 mile = 1609 m to find an answer for the speed of sound. %3D

(a) Use the distance and velocity data in Figure 3.64 to find the rate of expansion as a function of distance. (b) If you extrapolate back in time, how long ago would all of the galaxies have been at approximately the same position? The two parts of this problem give you some idea of how the Hubble constant for universal expansion and the time back to the Big Bang are determined, respectively. Figure 3.64 Five galaxies on a straight line, showing their distances and velocities relative to the Milky Way (MW) Galaxy. The distances are in millions of light years (Mly), where a light year is the distance light travels in one year. The velocities are nearly proportional to the distances. The sizes of the galaxies are greatly exaggerated; an average galaxy is about 0.1 MlY across.
(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)

I do not understand but this essey relat to physic and I do not know how to solve it and I do not have time eunogh please help me
No need for explanation, just the answer would be good. ASAP I’ll rate.
we see a bolt of lightening and 4 seconds later we hear the thunderclap. if the speed in the air is 330m/s. how far away is the lightening?
