V square - u square = 2as. here s=distance
here v squared= 18 squared=324
u squared=12 squared=144
324-144=2×36×s
180=72s
hence distance=2.5
It is charged because the number of electrons do not equal the number of protons in the atom or molecule. ... When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION.
ΔT= 81°C was the increase in temperature.
<h3>
steps</h3>
As evidenced by energy conservation
To increase its temperature, all of its kinetic energy will be converted to thermal energy.
ΔT
then divide both sides by the object's mass.
ΔT
therefore, a temperature shift is described as
ΔT= 
ΔT= 
/ 2 x 387
ΔT= 81°C
ΔT= 81°C was the increase in temperature.

Answer:
They create enormous amounts of sound energy, much like explosion. When an aircraft passes through air, it creates a series of pressure waves just like the waves created by the boat. As the speed of aircraft increases these waves are forced to compress.
