Afrench submarine and a u. s. submarine move toward each other during maneuvers in motionless water in the north atlantic. the french sub moves at speed vf-50.0 km/h, and the us. sub at vu,-70.0 km/h. the french sub sends out a sonar signal (sound wave in water) at 1000 hz. sonar waves travel at 5470 km/h. (a) what is the signal's frequency as detected by the u. s. sub? (b) what fre- quency is detected by the french sub in the signal reflected back to it by the u. s. sub? frenche u. s vus fig. 16-22 problem 32.

1/0.14nm = 10^10/1.4 a lot

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
