During radioactive beta-decay, a neutron (1.6749x10-27 kg) at rest decays into a very slow moving proton (1.6726x10-27 kg) and a

Ne4ueva [31]

The speed of the electron emitted in the radioactive beta-decay is determined as 2.186 x 10⁶ m/s.

<h3>Speed of electron </h3>

The speed of the electron is determined from the total energy of the electron.

Assuming the emitted electrons are in first energy level, E = 13.6 eV

K.E = ¹/₂mv²

v² = 2K.E/m

v² = (2 x 13.6 x 1.6 x 10⁻¹⁹)/(9.11 x 10⁻³¹)

v² = 4.777 x 10⁻¹²

v = 2.186 x 10⁶ m/s

Which best describes the type of lens that would help someone with one of these eye conditions? Concave lenses would help someon

s2008m [1.1K]

Answer:

The answer is "Option a".

Explanation:

The concave lenses are there for narrow-sighted people, convex for the far people. In eyewear, curved lenses are used to rectify visibility. Since in nearsighted individuals the width between the eye lens as well as the retina is larger than should be, these readers can't clearly distinguish distant things.
