Answer:
343.98 nm is the longest wavelength of radiation with enough energy to break carbon–carbon bonds.
Explanation:
A typical carbon–carbon bond requires 348 kJ/mol=348000 J/mol
Energy required to breakl sigle C-C bond:E
where,
E = energy of photon
h = Planck's constant = 
c = speed of light = 
= wavelength of the radiation
Now put all the given values in the above formula, we get the energy of the photons.
343.98 nm is the longest wavelength of radiation with enough energy to break carbon–carbon bonds.
Precipitation tends to be HIGHER on the WINDWARD SIDE of the a mountain because water vapour CONDENSES as it rises there.
There are two sides to every mountain, the windward and the leeward sides. The windward side experience more rainfall while the leeward side is drier and warmer.
Answer:
The speed of wavelength is 3.0 ×10³ m/s.
Explanation:
Given data:
De Broglie wavelength = 132 pm (132×10⁻¹² m)
Speed of wavelength = ?
Solution:
Formula:
λ = h/mv
λ = wavelength
h = planck's constant
m = mass of proton
v = speed
now we will put the values in formula.
132×10⁻¹² m = 6.63 ×10⁻³⁴ j.s / 1.67 ×10⁻²⁷ kg × v
v = 6.63 ×10⁻³⁴ j.s / 1.67 ×10⁻²⁷ kg × 132×10⁻¹² m
j = kg m²/s²
v = 6.63 ×10⁻³⁴ kg m²/s / 1.67 ×10⁻²⁷ kg × 132×10⁻¹² m
v = 6.63 ×10⁻³⁴ kg m²/s / 220.44 ×10⁻³⁹ kg.m
v = 0.03×10⁵ m/s
v = 3.0 ×10³ m/s
The speed of wavelength is 3.0 ×10³ m/s.
