<span>Yes, the vast majority of an atom is indeed empty space. Most of it's mass is centered in the nucleus. Flying around the nucleus are the electrons, but they're very very far away (on an atomic level anyway). Most of the atom is the space between the nucleus and the electrons.</span>
B. it was necessary to see data from more plants before the conclusion could be accepted.
An energy equation is a chemical equation which involves the energy that is evolved or absorbed in the reaction.
<h3>What is energy?</h3>
The term energy refers to the ability to do work. An energy equation is a chemical equation which involves the energy that is evolved or absorbed in the reaction.
This question is incomplete as the former energy equation is not shown. However, such equations can be used to know an endothermic or exothermic reaction.

Answer:
a).
Wmin= 2471.03 J
W=1603.01 J
Explanation:
Weight, w= 2267 N
Minimum work 'h' is the distance the refrigerator is raised h=1.09m
The motion is no frictional force so, the magnitude of the force with a angle of 45.0° is find using:
Explanation:
For equilibrium, 
.
So, 
= 0
= 
= 705.6 N
Also, for equilibrium 
= 0
= 0
or, 
= 
= 176.4 N
Thus, we can conclude that the tension in the first rope is 176.4 N.
