As the substance gains thermal energy, the density of a fluid decreases.
When the particles of a substance have more thermal energy, they move faster and farther apart.
Density is the closeness of the particles of a substance. The closer the particles, the higher the density.
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.

Answer:
Th-234, Pa-234
Explanation:
In alpha decay, 2 protons and 2 neutrons are lost. So U-238 would become Th-234.
In beta decay, one neutron is turned into a proton. So Th-234 would become Pa-234.
The atomic bomb explosion, depends on the energy released, W, the elapsed time, t, and the air density which altogether lead to the vaporisation of the contents within the mushroom cloud created.
<h3>What is an atomic bomb?</h3>
An atomic bomb is type of nuclear weapon that releases a vast amount of energy upon explosion in the form of fission reaction.
During an explosion of atomic bomb, a cloud of mushroom fire is formed which vaporises anything found within it. The extent of destruction depends on:
Therefore, the atomic bomb explosion, depends on the energy released, W, the elapsed time, t, and the air density which altogether lead to the vaporisation of the contents within the mushroom cloud created.

Answer:
2.0 s, 200 m
Explanation:
Time to hit the ground depends only on height. Since the plane is at the same height, the weight lands at the same time as before, 2.0 s.
Since the plane is going twice as fast, the weight will travel twice as far (ignoring air resistance). So it will travel a horizontal distance of 200 m.
