Average velocity of Mike Phelps swimming 100 m race in the 50 m long pool (2 laps) is approximately equal to * A. 0 m/s
B. 1 m/s
C. 2 m/s
D. 4 m/s

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

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

= final temperature = ?

using the equation
