An 'alpha particle' is the same thing as the nucleus of a helium atom ...
a little bundle made of 2 protons and 2 neutrons.
A 'beta' particle is an electron.
The mass of an alpha particle is more than 7,000 times the mass of
an electron, so it certainly takes more energy to get it moving.
Ignoring air resistance . . .
After the bomb is released, tangential (horizontal) acceleration is zero,, normal (vertical) acceleration is 9.8 m/s^2 down (gravity).

Answer:
The wavelength of the sound waves are, λ = 26.92 m
Explanation:
Given data,
The frequency of the sound waves, f = 13 Hz
The speed of sound waves in air, v = 350 m/s
The velocity of the wave in the medium is equal to the product of its wavelength and its frequency.
The formula for the wavelength of the waves is,
λ = v / f
Substituting the given values in the above equations,
λ = 350 m/s / 13 Hz
= 26.92 m
Hence, the wavelength of the sound waves are, λ = 26.92 m
Answer:
<h3>» equal , opposite</h3>
Explanation:
For every force there is one that is <u>equal</u><u> </u>
in size but <u>opposite</u> in direction.
<h3>because , </h3>
<h3>Newton's Third law states that</h3>
<h3>For every force, there is another force of equal magnitude, acting in the opposite direction.</h3>
