Out of the options, glass is the least fluid. The proof of this also lies in the fact that glass is the most difficult to melt out of all of the mentioned substances, and melting point gives us a rough estimate of the strength of intermolecular forces.
<h3><u>Answer;</u></h3>
<u> = 1319.45 Joules </u>
<h3><u>Explanation;</u></h3>
Kinetic energy is the energy possessed by a body in motion;
It is given by the formula; 1/2mv², where m is the mass of the body and v is the velocity.
mass = 89.5 kg and v =5.43 m/s
Therefore;
Kinetic energy = 1/2 × 89.5 × 5.43 ²
<u> = 1319.45 Joules </u>

double layered vacuum seal as the thermal insulators to make a liuqid hot when it cold and keep it cold when its hot.
Explanation:
Answer:
mass number
Explanation:
The sum of the protons and neutrons in an atom equals the mass number of such an atom.
- Mass number is the mass of an atom.
- The mass of an atom is concentrated in the nucleus
- The particles in the nucleus are the protons and neutrons.
So;
Mass number = number of protons + number of neutrons.
