C) 24
Explanation:
When a radioactive isotope of Vanadium, V decays by producing a beta particle and gamma rays, the atomic number will be 24.
Vanadium is the 23rd element on the periodic table.
It has a mass number of 51.
atomic number is 23
⁵¹₂₃V
A beta particle is symbolized as °₋₁B
Gamma rays are represented by Y
Now to the equation:
⁵¹₂₃V → ₐⁿK + °₋₁B + Y
In a nuclear reaction the mass an atomic number is conserved
51 = n + 0
n = 51
23 = a -1
a = 24
We can see that the nuclide formed will have an atomic number of 24

Answer:700 nm corresponded to light in the red range and 450 nm corresponded to light in the blue range.
Explanation:The wavelengths of the visible spectrum are usually between 400 nm and 700 nmn with the the rays of red light having a longer wavelength, and blue light rays having shorter wavelengths. The red light has a low frequency of about 405–480 THz and , blue light has a higher frequency in the range of 620–680 THz. This is due to the inverse relationship between wavelength and frequency which also occurs betwwn wavelength and energy of light rays with the red light having less photon energy of about 1.65–2.00 eV and the blue light with high energy photons of about 2.64–2.75 eV.
Red light can be employed in the photosynthesis in plants as it helps in formation of flowers and the production of fruits. Blue light also is important in the production of chlorophyll and can cause a healthy and strong stem and leaves in excess exposure.
I think you don’t need the help anymore so can I just take these real quick ?
It’s the 3rd one :)
Hope this helped
