Question

The speed of the incoming water is 25 cm/s and the cross-sectional area of the hose carrying the water is 2.0 cm2. 1) Determine the time required for a 25-L container to be filled with water. (Express your answer to two significant figures.)

Answer 1

Answer:

The time taken is  $t = 500 \ s$

Explanation:

From the question are told that

  The speed of the incoming water is  $v = 25 cm/s$

  The cross-sectional area of the host pipe is  $a = 2.0 cm^2$

Generally the rate at which the container is been filled is mathematically represented as

         $\r V = v * a$

=>      $\r V = 25 * 2$

=>      $\r V = 50\ cm^3/s$

Generally $2.5 L = 25000 cm^3$

Generally the time taken is  mathematically represented as

      $t = \frac{25000}{50}$

=>   $t = 500 \ s$
