Answer:
ionic bonds formed from the electrostatic attraction between oppositely charged ions in a chemical compound.
Explanation:
Answer:
c. 2 m/s
Explanation:
The relationship between speed, frequency and wavelength of a wave is given by:

where
v is the speed of the wave
f is its frequency
is the wavelength
For the transverse wave in this problem, we have:
is the frequency
is the wavelength
Substituting these numbers into the equation, we find the speed of the wave:

B . light is <span>the physical energy that stimulates sight</span>
