Water is being sprayed from a nozzle at the end of a garden hose of diameter 3.5 cm. If the nozzle has an opening of diameter 0.9 cm, and if the water leaves the nozzle at a speed of 11 m/s, what is the speed (m/s) of the water inside the hose? Round your answer to 4 decimal places. (question will be manually graded)

A garden hose is attached to a water faucet on one end and a spray nozzle on the other end. The water faucet is turned on, but the nozzle is turned off so that no water flows through the hose. The hose lies horizontally on the ground, and a stream of water sprays vertically out of a small leak to a height of 0.86 m Part A What is the pressure inside the hose?

Sometime around 2022, astronomers at the European Southern Observatory hope to begin using the E-ELT (European Extremely Large Telescope), which is planned to have a primary mirror 42 m in diameter. Let us assume that the light it focuses has a wavelength of 520 nm. (1 light-year =9.461x 1015 m) Note: Jupiter's Diameter di 1.43 x 108 m 1) What is the most distant Jupiter-sized planet the telescope could resolve, assuming it operates at the diffraction limit?

The question concerns water flowing in or from a hose. The cross section of the hose is circular. The circumference of a circle is 2πR and the area of a circle is πR2, where R is the radius of the circle. 1 milliliter = 1 cm3. If the inner diameter of the hose is 1.2 cm, but you partially cover the opening of the hose leaving an open area of 0.3 cm<sup>2 </sup>at the end of the hose. The water...
