Answer:
Explanation:
c= carbon, h= hydrogen, o= oxygen
It lowers density thats why its able too float :)
Answer:
All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude. A wave can be described by its length, height (amplitude) and frequency. All waves can be thought of as a disturbance that transfers energy.
Frequency= 1/period
hence ans= 1/0.25
= 4s
