A curtain hangs straight down in front of an open window. A sudden gust of wind blows past the window; and the curtain is pulled out of the window. Which law, principle, or equation can be used to explain this movement of the curtain? a. Poiseuille's law
b. Bernoulli's equation
c. the equation of continuity
d. Archimedes' principle
e. Pascal's principle

Option B is the correct option.

Explanation:

The phenomenon of the curtain to pull out of the window can be explained using Bernoulli's equation.

According to Bernoulli's principle,when the speed of moving fluid increases the pressure within the fluid decrease.When wind flows in the outside window the pressure outside window decreases and pressure inside the room is more.So the curtain moves outside because of low pressure.

Hope this helps...

Good luck on your assignment...

it would be c. predictability
