Question

When a vehicle moves very fast, a region of ___ is created behind the vehicle.

• A. low pressure
• B. high pressure
• C. zero pressure
• D. high temperature

Answer 1

The correct option is A

low pressure

According to Bernoulli's Principle, the pressure of fluids decreases with the increase in velocity. So, when a vehicle moves very fast, a low-pressure region is created behind it temporarily. Wind moves from a region of high pressure to a region of low pressure. As a result, wind nearby rushes into the low-pressure region and fill the place.
