Answer:
A. 29.4 Joules
Explanation:
Given parameters:
Mass of the book = 1.5kg
Height of lift = 2m
Unknown:
Potential energy acquired = ?
Solution:
Potential energy is the energy due to the position of a body.
Mathematically;
Potential energy = mgh
m is the mass of the body
g is the acceleration due to gravity = 9.8m/s²
h is the height
Potential energy = 1.5 x 9.8 x 2
Potential energy = 29.4J
The answer is actually True. I just took the quiz.
The three
basic economic questions are the following:
<span>1. </span>What goods and services are to be
produced
<span>2.
</span>How the
products will be produced
<span>3. </span>Who gets what is produced/
Who will use the
products produced
Therefore,
letter D, who will produce the products is the exception of the basic economic
questions.
