Alpha emission is the process results in a change in mass number. Option B is correct.
<h3>What is mass number?</h3>
The total number of protons and neutrons in an atomic nucleus is known as the mass number, often known as the atomic mass number or nucleon number.
It's about the same as the atom's atomic mass, expressed in atomic mass units.
The alpha particle is a helium nucleus with two protons and two neutrons in an alpha decay or alpha emission. The number of protons and neutrons is reduced by two as a result of this action.
The quantity of protons and neutrons is affected by gamma emission descent. Also, while electron capture has no effect on the number of neutrons, it does raise the 1 also number of protons by one.
Alpha emission is the process results in a change in mass number.
Hence option B is correct.

1. Rainbow (white light is split into its subsequent wavelengths)
2. Light enters through the cornea, is adjusted by the lens, the cones and rods of the retina are responsible for the perception of color and shadows, which are sent through the optic nerve to the occipital lobe of the brain.
3. Sound waves are intercepted by the pinna, travels through the auditory canal, reverberates on the eardrum, the vibrations travel through the ossicles of ear (hammer, anvil and stirrup), continuing to the cochlea and are sent through the auditory nerve to the brain.
4. A medium
5. Vibrations
6. All
7. Faster
8.Their kinetic energy increases
9. Conduction, convection and radiation
10. The heating of metals in the mantle, creates a current which slowly moves the plates above it.
Answer:
It is cause by radiation that's the answer
Explanation: the heat project sun rays towards the popcorn which causes it to pop
Hooke's law is stated as: F = -kx
Where:
F = Force to compress or extend a spring (unit N)
k = Spring constant
x = displacement of spring
Or to help you in your native language:

Answer:
The frequencies the other string could have are 258.4 Hz and 261.6 Hz.
Explanation:
Given;
beat frequency, Fb = 1.60 Hz
frequency of the first string, F₁ = 260.00 Hz
frequency of the second string, F₂ = ?
Beat frequency is given as;
Fb = F₂ - F₁ or Fb = F₁ - F₂
Fb + F₁ = F₂ or F₂ = F₁ - Fb
1.6 + 260 = F₂ or F₂ = 260 - 1.6
261.6 Hz = F₂ or F₂ = 258.4 Hz
Therefore, the frequencies the other string could have are 258.4 Hz and 261.6 Hz.
