Answer:

C. The model does not show the true size of an atom.

Explanation:

The model can be described or explained as a physical representation of an unseen or yet to build structure or substance. The model will show the aim of the people that want to create a thing.

In this sense, the limitation of a model is that it will not actually give you the true size of the thing it is being used to represent. This means that it won't give the through size of the atom.

larisa86 [58]

Answer:

The correct answer is - C. Multiply 500 by 1.5.

Explanation:

Given:

Force to move a desk = 500 N

weight of desk = 300 N

displacement = 1.5 meters

work done by Tine = ?

Formula:

work done (W) = F*d

where F is the force applied on the desk and d is the displacement of the desk.

Solution:

As the displacement is perpendicular to the weight of the desk, therefore, the work done by weight is zero. The work done to the displacement of the desk would be =

W = F*d

= 500*1.5

= 750 J

Thus, the correct answer would be option C.
