The correct answer is:
a positron is emitted when proton converts to a neutron.
The reaction can be described as following:
₁¹p (proton) → ₀¹n (neutron) + ₁°e (positron or ₁⁰β)
Positron is an antiparticle of a β particle (₋₁°β), which means it has an oposite charge to it, but same mass.
Answer:
Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. Newton observed that color is not inherent in objects. Rather, the surface of an object reflects some colors and absorbs all the others. We perceive only the reflected colors.
Answer:
3.23 atm
Explanation:
Use the equation P₁V₁=P₂V₂. P₁ and V₁ are initial pressure and volume. P₂ and V₂ are final pressure and volume. Solve for P₂.
(1.88 L)(3.81 atm) = (2.22 L)(P₂)
7.1628 L*atm = (2.22 L)(P₂)
P₂ = 3.226 atm
The molar absorptivity is
Molar absorptivity is defined as the measure a compound's ability to absorb light of a specific wavelength. It is represented by the constant/symbol 'ε'.
The molar absorptivity is given by :
A = εcl
where A is the absorbance
ε is the molar absorptivity
c is the molar concentration of the compound
and l is the path length
here, the molar concentration of the solution is 0.16 mol
and the path length is 1 cm
to find the molar absorptivity , one must know the absorbance of the material.
