When you increase the frequency of the waves (assuming amplitude is held constant), the energy of the waves will increase, while wavelength will decrease.. Increase the frequency the light goes toward violet, decrease it and it goes toward red.
The surface or material that underlies a two-dimensional work of art is called the support.
Answer;
= 4.49 g/cm³
Explanation;
Density = Mass / Volume
mass = 1.41 kg,
volume = 0.314 L
but; 1 kg = 1000 g and 1 L = 1000 mL
Thus;
Density = 1.41 kg/0.314L
Density = 4.49 kg/L (1000g/ 1kg)(1L/1000cm^3)
Density = 4.49 g/cm^3
It grows... as expected of a muscle...
Answer: Option (c) is the correct answer.
Explanation:
Atomic number of hydrogen is 1 and one dot in its lewis structure displays only one electron. So, in order to complete its octet it needs one more electron.
Atomic number of carbon is 6 and its electronic distribution is 2, 4. Carbon needs 4 more electrons in order to complete its octet.
Atomic number of oxygen is 8 and its electronic distribution is 2, 6. In order to complete octet, oxygen needs 2 more electrons.
Atomic number of fluorine is 9 and its electronic distribution is 2, 7. In order to complete octet, fluorine needs 1 more electron.
Hence, we can conclude that out of the given options, lewis dot structure of oxygen atom needs 2 more electrons in its outermost shell.
