Explanation:
a. The Hooke's Law states
, where 
is the force, 
the spring constant and 
the displacement, Knowing the force and the displacement you can find :
b. The work done by a force 
that moves along a displacement 
is:
Then
(Hooke's Law)
Work needed to go from 
to 
c. Work needed to go from to 
d. Work needed to go from 
to
Answer;
The above statement is false
Explanation;
Symmetrical distribution, commonly known as symmetric distribution or normal distribution, is typically unimodal, meaning it shows only one peak in graph form.
It is a type of distribution where the left side of the distribution mirrors the right side. By definition, a symmetric distribution is never a skewed distribution.
All normal distributions are symmetric and have bell-shaped density curves with a single peak.
Answer:
Smoother surfaces, and less contact between objects.
Explanation:
Smoother surfaces create less friction and drag among the object pulled, so we definitely need those kinds of surfaces to reduce friction.
