Question

A garden hose having an internal diameter of 2cm is connected to a lawn sprinkler with 20 holes, each 0.2 cm in diameter. If the water in the hose has a speed of 2 space m s to the power of negative 1 end exponent, the speed with which it leaves the sprinkler holes is

  1. 5 ms to the power of negative 1 end exponent
  2. 10 ms to the power of negative 1 end exponent
  3. 20 ms to the power of negative 1 end exponent
  4. 4 ms to the power of negative 1 end exponent

The correct answer is: 10 ms to the power of negative 1 end exponent
