Water falls without splashing at a rate of 0.240 L/s from a height of 3.40 m into a 0.780-kg bucket on a scale. If the bucket is originally empty, what does the scale read 2.30 s after water starts to accumulate in it?

A garden hose has an inner radius of 1 cm, is connected to a spray nozzle (radius: 0.4 cm). If this hose is connected to a house capable of  delivering 9 L/s, what is the velocity of the water in the hose?

An airplane has wings, each with area 3.85 m2, designed so that air flows over the top of the wing at 248 m/s and underneath the wing at 226 m/s.   Approximately what size wings would an aircraft need on Mars if its engine generates the same differences in speed as in the "Practice It" and the total mass of the craft is 300 kg? The density of air on the surface of Mars is approximately one percent Earth's density at sea level, and the acceleration of gravity on the surface of Mars is about 3.8 m/s2. ______________m2

While sitting on a boat floating on a small pond, you drop an anchor into the water. The anchor immediately sinks to the bottom. Does the presence of the anchor in the water cause the pond to get shallower, deeper or stay the same compared to when the anchor was on the boat? Explain your answer.

To water the yard, you use a hose with a diameter of 3.6 cm. Water flows from the hose with a speed of 1.3 m/s. If you partially block the end of the hose so the effective diameter is now 0.52 cm, with what speed does water spray from the hose?

A hippo is dozing under water with only its small nostrils sticking out. It has a mass of 3000 kg and a volume of about 2.98 m3 after exhaling. How much force in Newtons does it exert on the ground of the pool (fresh water, density 1g/cm3)?

E 3. A spring is attached to the bottom of an empty swimming pool, with the axis of the spring oriented vertically. An 8.60- kg block of wood (density = 770 kg/m³) is fixed to the top of the spring and compresses it. Then the pool is filled with water, completely covering the block. The spring is now observed to be stretched twice as much as it had been compressed. Determine the percentage of the block's total volume that is hollow. Ignore any air in the hollow space. % 20 C $ 27 R 888 V % 5 T G tv MacBook Air 6: B P H & F7 N 8 M ( 9 AO K O P zoom CIA by m EA 04 M wies or the puffer delete 21 A A

A company needs to pump coconut oil (den: 924 kg/m^3) from the import truck to its holding tank 17 meters above the ground.  If the pump that is used is able to create 3 ATM of pressure, what will be the velocity of the oil as it enters the tank?
