The frequency of the musical note F3 is 1.85 102 hertz. What is its period? A 5.40 x 10-3seconds
B. 1.05 x 10-3 seconds
C. 3.09 x 10-3 seconds
D. 5.31 x 10-1 seconds

0.0054 s

Explanation: There is an inverse relation between the frequency  and the period  of a wave (a sound wave in this case):

T=1/F

Where f = 1.85 (10)² H z

Hence : T = 1/1.85 (10)² H z T =0.0054s

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

answer: they produce more slow than unicellular organisms.
