To solve this problem it is necessary to apply the concepts related to energy as a function of voltage, load and force, and the definition of Force given by Newton in his second law.
By definition we know that force is equal to
F= ma
Where,
m = mass (at this case of an electron)
a = Acceleration
But we also know that the Energy of an electric object is given by two similar definitions.
Where,
F= Force
q = Charge of proton/electron
V = Voltage
d = Distance
Equating and rearrange for F,
The two concepts of force can be related to each other, then
Acceleration would be,
Replacing with our values we have that the acceleration is
Now through the cinematic equations of motion we know that,
Where,
Final velocity
Initial velocity
a = Acceleration
x = Displacement
Re-arrange to find v_f,
Therefore the electron's speed when it is 0.1 cm from the negative plate is
The study of the atom contributed to our understanding of the periodic table of the elements in the following way: experiments that identified characteristics of atoms provided scientists with atomic weights and atomic numbers, which were used to organize the periodic table.
<h3>PERIODIC TABLE:</h3>
The periodic table is an organized table of the chemical elements arranged in order of their atomic number
The periodic table consists of rows called periods and columns called groups. Each element in the periodic table is made up of its own individual atom.
Hence, the experiments conducted on these atoms provided the atomic numbers and masses used as a template to organize each element in the periodic table.

The centripetal force increases by a factor of 4
Explanation:
Let the centripetal force be F
F =mv^2/r
m= mass of the object
v = linear velocity of the object
r = radius of the circular path
but v = 2πr/T = 2 * 3.142 * 0.147 / 0.388
v = 2.38 m/s
F = 0.0113 * (2.38)^2/0.147
F= 0.435 N
if v= 2v
Then;
F = m(2v)^2/r
F = m4v^2/r
F= 4mv^2/r
The centripetal force increases by a factor of 4
There's no way to tell for sure which plant will grow faster, because
we don't know if a plant gets any benefit from red light.
But we do know for sure that it won't be the one we shine green light on.
We know that green light is no use to green plants at all ... that's why
when green light falls on them, they don't even bother absorbing it.
They just let it bounce off, and that's why they look green to us.
