Mekhanik [1.2K]

When a candle is burning and wind is blowing it on one side of the flame, which causes the flame to bend towards the wind is an example of Bernoulli’s principle. The principle explain that the higher the speed, the lower the pressure becomes. When you blow against one side of the flame, you are creating an area of low pressure. The relatively high-pressure air on the other side of the candle will rush over to fill the area of low pressure that causes the flame to be pushed in the direction of the blowing.

Clara rushes 30m to a truck then turns and walks back. Total travel is 120s what is her average velocity?

navik [9.2K]

Taking into account the definition of velocity, Clara's average velocity is 0.5 m/s.

<h3>Definition of velocity</h3>

Velocity is a physical magnitude that relates the displacement of an object, the time it takes to make this change in position and direction. So it is considered a vector magnitude.

In other words, the velocity can be defined as the amount of space traveled per unit of time with which a body moves, considering the direction, and can be calculated using the expression:

velocity= distance traveled÷ time

<h3>Average velocity of Clara</h3>

Clara rushes 30 m to a truck then turns and walks back. Total travel is 120s. Then, you know:
