Answer:
average acceleration is 1.365 × 
m/s²
Explanation:
given data
initila speed u = -32.2 m/s
final speed v = 21.6 m/s
time taken t = 0.00394 s
solution
we get here average acceleration that will be express as
v = u + at ..........................1
put here value and we get
21.6 = -32.2 + a × 0.00394
solve it we get
a = 1.365 × m/s²
so average acceleration is 1.365 × m/s²
Dubnium is a synthetic element ... Number 105. It can be created
in a laboratory but it's not found in nature.
Fifteen (15) different isotopes of Dubnium have been created. They all
have 105 protons in the nucleus of every atom, but they have anywhere
from 256 to 270 neutrons in each nucleus.
The most stable isotope of Dubnium is ²⁶⁸Db , with 163 neutrons in the
nucleus. That form of Dubnium atom has a 50-50 chance of surviving
for around 28 hours before it falls apart.

Answer:
Explanation:
Hydrogen and hydroxide ions reacts to form water in a neutralisation reaction
Its a tightly-packed particles gain energy, allowing them to move more freely.
The correct answer is<span> gases, energy, temperature, phases
Gravity and nuclear forces are not encompassed in the kinetic molecular theory as it deals with movement and behavior of gas molecules. It does not include their conversion to other types of energy or anything similar. </span>
