After your school's team wins the regional championship, students go to the dorm roof and start setting off fireworks rockets. The rockets explode high in the air and the sound travels out uniformly in all directions. If the sound intensity is 2.22 10-6 W/m2 at a distance of 243 m from the explosion, at what distance from the explosion is the sound intensity half this value

If I1 is the intensity at a distance 150 m from the source and I2 is the intensity at a distance of d m from the source ,

I1 *150^2 = I2 *d^2

d^2 =[ I1 / I2 ]*150^2

[I1 / I2] = 1.9 /0.8= 2.375

d^2 = 2.375*150^2

d =231.17 m

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
