- Problem 1: Suppose you have a coffee mug with a circular cross section and vertical sides. What is its inside radius if it holds 375 g of coffee when filled to a depth of 7.5 cm? Assume coffee has the same density as water, 10³ kg/m³.4. A garden hose having an internal diameter of 3.5 cm is connected to a lawn sprinkler that consist merely of an enclosure with 12 holes, each 0.5 cm in diameter. If the water in the hose has a speed of 3 m/s, at what speed does it leaves the sprinkler holes?Please answer question 7
- At a given instant, the blood pressure in the heart is 1.1 x 104 Pa. If an artery in the brain is 0.38 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow. Number Type your answer here Units Choose your answer hereYour dorm has an amateur hour every Friday night. Since you have a tremendous lung capacity, you challenge everyone to a lung capacity competition which is conducted by blowing air through one straw which in turn pulls water up through another straw, as shown in the figure. The straws are identical and have a diameter of 0.58 cm, you are able to exhale 1.4 liters of air through the horizontal straw in as little as 2 seconds, and the density of air is 1.29 kg/m³. Determine the following. (a) speed of the air as it travels through the horizontal straw m/s (b) height to which water rises in the vertical straw cmA student fills a tank of radius r with water to a height of h1 and pokes a small, 1.0 cm diameter hole at a distance h2 from the bottom of the tank. The water flows out of the small hole into an empty, 0.2 m-diameter container placed below the tank. The student uses a garden hose to keep the water level in the tank at the original height. What is the velocity of the water as it leaves the hole near the bottom of the tank? let h1=0.55m let h2=0.12m r=0.5m 2. What is the volume flow rate of water from the garden hose into the tank? (Hint: What is the flow rate out of the tank?) 3. After 60 seconds of operation, what is the water pressure at the bottom of the container that is being used to catch the water leaving the tank? let h=1.7m
- At a given instant, the blood pressure in the heart is 1.1 x 104 Pa. If an artery in the brain is 0.38 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow. Number Type your answer here Units Choose your answer hereA popular pool toy allows the user to push a plunger to compress water in a barrel with a diameter of 3.5 cm. The water is compressed with a speed of 1.9 m/s and emerges from a small opening with a speed of 12 m/s. What is the diameter (in mm) of the opening? Assume the toy is oriented horizontally. mmQuestion 3 (1 point) 1.00 L (0.00100 m*3) of water is poured into a large container. 100 g of ice is added to the container. The ice floats freely and does not touch the bottom of the container. The densigy of ice is 917 kg/m. When the ice melts, what happens to the level of the water in the container? The water level rises. The water level stays the same. The water level falls. There is not enough information to tell.
