Question: Which of the following is a non-Newtonian fluid?
Options:
Water
Glycerin
Cornstarch in water
Mercury
Correct Answer: Cornstarch in water
Solution:
Cornstarch in water exhibits non-Newtonian behavior, as its viscosity changes with the applied shear stress.

Questions & Step-by-Step Solutions
Which of the following is a non-Newtonian fluid?
Correct Answer: Cornstarch in water
Step 1: Understand what a non-Newtonian fluid is. A non-Newtonian fluid is a fluid whose viscosity changes when stress or force is applied.
Step 2: Identify examples of non-Newtonian fluids. Common examples include cornstarch mixed with water, ketchup, and toothpaste.
Step 3: Focus on cornstarch in water. When you mix cornstarch with water, it behaves differently under different forces.
Step 4: Apply a force to the cornstarch and water mixture. If you stir it slowly, it flows easily, but if you hit it or apply a lot of force, it becomes thick and hard to move.
Step 5: Conclude that cornstarch in water is a non-Newtonian fluid because its viscosity changes with the amount of force applied.
