I would say they design and build things.
Answer:
The correct answer is
C. 6 Protons
Explanation:
Carbon is a nonmetallic element that is available in both organic and inorganic compounds.
Carbon belongs to group 14 elements in the periodic table,carbon is a chemical element with the symbol C and atomic number 6, it can form long chains with its own atoms, a feature called catenation.
Two allotropes of carbon available are diamonds and graphites, which have different crystalline structures
The physical properties of carbon vary widely with the allotropic form.
examples are.
- Graphite, diamonds and coal are all nearly pure forms of carbon
- Diamond is highly transparent. Graphite is opaque and black
- Diamond is one of the hardest substances known to man. Graphite is soft and often used as the "lead" in lead pencils
- Diamond has a very low electrical conductivity. Graphite is a very good conductor
- Very brittle, and cannot be rolled into wires or pounded into sheets
Answer:
A = 0.023 m
Explanation:
The relation between the frequency of a radiation and its wavelength is given by the following expression.
where,
c is the speed of light (it has a constant value of 3.00 x 108 m/s)
A is the wavelength of the radiation v is the frequency of the radiation
In this case, the frequency is 13 GHz = 13 x
10° Hz = 13 x 1o° s-
The wavelength associated with this frequency is:
A = c/v = (3.00 x 10° m/s)/(13 x 10° s-") = 0.023
