I believe the coma is formed from the dust and gas from a comet.
Hope this helps!! :)
Answer:
633 nm
Explanation:
E = Energy difference = 1.96 eV
c = Speed of light = 3×10⁸ m/s
h = Planck's constant = 6.626×10⁻³⁴ J/s
Converting eV to J
1 eV = 1.6×10⁻¹⁹ J
1.96 eV = 1.96×1.6×10⁻¹⁹ Joule = 3.136×10⁻¹⁹ Joule
Photon energy equation
∴ Wavelength of light emitted by this laser is 633 nm
The answer that best fits the blank provided above is MECHANICAL ADVANTAGE. Given that in simple machines, output should not be greater than the input therefore, the Mechanical advantage of a simple machine has its input forces multiplied instead which results in force amplification. The answer for this would be option A.
