Heat engines are less than 100% efficient because absolute zero cannot be reached
Answer:
the value of acceleration as a body moves with an uniform speed is zero
The correct answer is Model A shows the three-dimensional shape of the molecule, but Model B does not.
Explanation:
Model A and B show the structure of a molecule. In the case of model A, the structure is represented through the use of three-dimensional shapes, while in model B the structure is represented using the letters of each element and showing how each element is connected to others.
In this context, one feature that makes model A better is that this represents the molecule using a 3D model, which is better to understand how the molecule looks like and what is its structure. Moreover, both models are alike because they show the number of atoms of each element, although model A does not show the types of elements.
The answer would be "the vector sum of forces acting on a particle or body."
Hope that helped ^^
