If the velocity of the liquid rises the pressure of the liquid must drop according to the __ principle. a. Bernoulli b. Woodruff c. Mallory d. Faraday

## Step 1<br />The problem is asking us to identify the principle that states that if the velocity of a liquid increases, the pressure of the liquid must decrease. This is a fundamental concept in fluid dynamics, a branch of physics.<br /><br />## Step 2<br />The Bernoulli principle is the correct answer. This principle, named after Daniel Bernoulli, states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.<br /><br />## Step 3<br />The other options, Woodruff, Mallory, and Faraday, are not related to this principle. Woodruff is a type of valve, Mallory is a company that manufactures batteries, and Faraday is a scientist known for his work in electromagnetism.
