Ответ:
Visible light or electromagnetic radiation within 400nm to 700nm is responsible for colour of the spectrum.
Explanation:
The electromagnetic spectrum contains radiations of varying wavelength. The radiations with the lowest energy are characterised by the longest wavelength.
Within this spectrum lies the visible light which enables us to see a different colour. The radiations within the range 400nm to 700nm are included in the visible spectrum.
While violet lies at the 400nm spectrum part red colour lies at 700nm part. As the wavelength of the radiation transverses between 400-700 nm, the colour of the object changes accordingly.
Ответ:
E = 4.9735 × 10⁸ J
Explanation:
Given:
Charge transferred, q = 46.7 C
Potential difference, ΔV = 10.65 MV = 10.65 × 10⁶ V
Now, the relation between the energy (E) , charge (q) and the potential difference is given as:
E = qΔV
on substituting the values in the above equation, we get
E = 46.7 × 10.65 × 10⁶ V
or
E = 4.9735 × 10⁸ J
Hence, the energy released is 4.9735 × 10⁸ J
