I think is e 400 , im not sure
By taking cuttings from it and replanting it
Answer:
2.5 x 10⁻⁹ m
Explanation:
E = Energy of photon = 500 eV = 500 x 1.6 x 10⁻¹⁹ J
c = speed of photon = 3 x 10⁸ m/s
λ = wavelength of photon = ?
Energy of photon is given as
inserting the values
λ = 2.5 x 10⁻⁹ m
Alpha decay is the term that is used to describe a type of radioactive decay that involves the evolution of a helium nucleus.
<h3>What is alpha decay?</h3>
The term alpha decay is the term that is used to describe a type of radioactive decay that involves the evolution of a helium nucleus. In this case the question is incomplete but I will try to paint a general picture of alpha decay.
The general equation for an alpha decay will produce a daughter nucleus that has an atomic mass less by four units and atomic number that is less by two units.
