Two strings of equal length are stretched out with equal tension. the second string is four times as massive as the first string. if a wave travels down the first string with velocity v , how fast does a wave travel down the second string?

mistakes are ok

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

friction

they us to move forward and backwards
