The answer would be H and C only. Hydrocarbons are organic compounds consisting entirely of carbon and hydrogen. They are the simplest form of organic compounds. They are joined together by covalent bonds. They can be straight-chain, cyclic or branched chain.
Answer:
B. Conductivity.
Explanation:
Conductivity is the quantity of heat passing per second through a slab of unit cross-sectional area when the temperature gradient between the two faces is unity when put in heat.
According to Einstein the energy of photon is given by the equation,
E = hν = h . c/λ
where h is Planck's constant, c is the speed of light, ν is the frequency of light and λ is the wavelength of light.
Given, wavelength = 608 nm = 608 x 10⁻⁹ m
Conversion factor: 1 nm = 10⁻⁹ m
c = 3 x 10⁸ m/s
h = 6.626× 10⁻³⁴ J.s
Substituting the data into the equation we get,
E = h . c/λ
E = 6.626× 10⁻³⁴ J.s x (3 x 10⁸ m/s) / 608 x 10⁻⁹ m
E = 3.27 x 10⁻¹⁹J
3.27 x 10⁻¹⁹J energy must be added to strontium to get it to produce 608 nm wavelength.
Convert: 6 cubic centimeters to fluid ounces. 2.03 0.203 0.00203 0.000203
=0.203
