Answer:
The frequency of wave is 0.125 Hz.
Explanation:
Frequency:
"It is an event repeat itself in a given period of time"
The unit of frequency is the Hz . If time is measured in seconds then frequency will be in Hz. Hz is equal to the per second.
Formula:
f = 1/ T
f = 1/ 8 sec
f = 0.125 Hz

Explanation:
The correct is tricky, be careful. The right is silicon dioxyde (SiO2)
Silicon Oxides are written in the form SiOx, (0 <x <2), so:
there is no silicon trioxygen and disilicon dioxygen.
SiO is called silicon monoxide and not monosiicon oxygen, so this proposition is false.
All that remains is the silicon dioxide (SiO2) that is written correctly.
Silicon dioxide can be synthesized but also exists in abundance in nature. Silicon (Si) represents about 26% of the Earth's crust. Silica (SiO2), the natural form of silicon dioxide, accounts for about 60%.
