Answer:
A
Explanation:
the nucleus is the center of the atom who controls the element.
The new absloute temperature should be 4t.
<h3>Temperature </h3>
The hotness of matter or radiation is expressed by the physical quantity known as temperature.
There are three different types of temperature scales: those, like the SI scale, that are defined in terms of the average translational kinetic energy per freely moving microscopic particle, like an atom, molecule, or electron in a body; those that solely depend on strictly macroscopic properties and thermodynamic principles, like Kelvin's original definition; and those that are not defined by theoretical principles but rather by useful empirical properties of particula.
Using a thermometer, one can gauge temperature. It is calibrated using different temperature scales, each of which historically defined itself using a different set of reference points and thermometric materials.

I would say gas, but I don't know enough about plasma to put it out. It's definitely not solids or liquids because their molecules are too close together to move freely. Gas or plasma! Sorry that I'm not sure.
Answer:
10m/s
Explanation:
a = v- u/ t
=> v = at + u
= -2 × 5 + 20
= 10m/ s. ( 72 km/ h = 20 m/ s)
