Answer:
a) 70,560 J
b) 88.2 N/m
Explanation:
The spring potential will equal the change in gravity potential
PS = PE = mgh = 80(9.8)(100 - 10) = 70,560 J
PS = ½kx²
k = 2PS/x² = 2(70560)/(100 - 50 - 10)² = 88.2 N/m

Recently, We've been discussing this specific topic in my RS class. So, there are many theories to explain the existence of the world such as the Big Bang, Evolution or the Creation story.
Although these are three different ideas, they can still be related or interconnected with one another in some way. For example, George Lemaintre's Big Bang explanation can be linked with the Creation story in ways such as God being present at the Big Bang or even God being the one to allow the Big Bang occur.
Furthermore, God might have created us as apes or monkeys then we evolved to become humans.
In conclusion, the universe couldn't have come to pass just like that, they're must be Scientific or Theological truths to back this up. The only thing is that people have their unique beliefs, according to their religion, culture and childhood background.
Answer:
Base
Explanation:
anything with a pH between 0-6 is an acid. pH of 7 means neutral. 8-14 means it is a base
hope I helped :)
