Agarden hose with an internal diameter of 2.5 cm is connected to a (stationary) lawn sprinkler that consists merely of a container with 28 holes, each 0.20 cm in diameter. if the water in the hose has a speed of 0.85 m/s, at what speed does it leave the sprinkler holes?

4.7433 m/sec

Step-by-step explanation:

Given data

the internal diameter of garden =2.5 cm =0.025 m

radius =  0.0125 m

it contains 28 holes each of diameter 0.20 cm =0.002 m

radius =0.001 m

from continuity equation

where A is area and V is velocity

0.85×=28 ××

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
