Answer:
Answer: Science and technology are relatively modern developments. For most of the past 50,000 years of civilization, there was religion, dogma, ritual an tradition. These kept civilization safe but prevented growth.
After the modern scientific method was developed during the Rennaisance, civil action took off.
Health, as expressed as life expectancies, has increased massively. Population growth has increased to levels thought impossible before. But yes, the environment has suffered.
Answer:
<h3>0.69</h3>
Explanation:
Using the Newtons law of motion;

Fm is the moving force = 400N
Ff is the frictional force = μR
μ is the coefficient of kinetic friction
R is the reaction = mg
m is the mass
a is the acceleration
The equation becomes;

Hence the coefficient of kinetic friction between the box and floor is 0.69
Friction causes kinetic energy to be converted into 'thermal energy'. The answer to this question is 'thermal energy'. An example would be if something is being rubbed against another object, there is friction and thermal energy will be produced. I hope this helps you on your assignment! You're welcome.
