Answer:

B. It acts to hold the vinegar and oil together in a colloid.

Explanation:

Egg yolk contains lecithoprotein and yolk is an emulsion. An emulsion is a temporary stable mixture of immiscible fluids. It functions as an effective and efficient emulsifying agent. It emulsifies by reducing surface tension and reduces the force which is needed to make the droplets that comprise an emulsion. Thus, egg yolk holds or stabilizes oil and vinegar together.

A woman holds a book by placing it between her hands such that she presses at right angles to the front and back covers. The boo
In-s [12.5K]

Answer:

Explanation:

In order to solve this problem we need to make a free body diagram of the book and the forces that interact on it. In the picture below you can see the free body diagram with these forces.

The person holding the book is compressing it with his hands, thus exerting a couple of forces of equal magnitude and opposite direction with value F.

Now the key to solving this problem is to analyze the equilibrium condition (Newton's third law) on the x & y axes.

To find the weight of the book we simply multiply the mass of the book by gravity.

W = m*g

W = 1.3[kg] * 9.81[m/s^2]

W = 12.75 [N]
