If the frequency of a wave increases from 2 Hz to 4 Hz without the wavelength changing, how will the wave speed change?

graph question answered .. you think better when you are relaxed and happy

massxgravity x heght=weightxheight= pe

4900=490xh

h=10

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

answer is slate

hope this
