Air is blown into a spherical balloon so that, when its radius is 6.50 cm, its radius is increasing at the rate 0.900 cm/s. (a) Find the rate at which the volume of the balloon is increasing. (b) If this volume flow rate of air entering the balloon is constant, at what rate will the radius be increasing when the radius is 13.0 cm? (c) Explain physically why the answer to part (b) is larger or smaller than 0.9 cm/s, if it is different.
A man drops a rock into a well, (a) The man hears the sound of the splash 2.40 s after he releases the rock from rest. The speed of sound in air (at the ambient temperature) is 336 m/s. How far below the top of the well is the surface of the water? (b) What If? II the travel time for the sound is ignored, what percentage error is introduced when the depth of the well is calculated?
ion 2 Unsaved The radius of an artery narrows from 1.10 cm down to 0.500 cm due to atherosclerosis. This results in a faster blood flow in the narrowed region. The average speed of the blood in the narrow region is 41.0 cm/s. Determine the average speed of the blood in the wide region. Give your answer in units of cm/s, accurate to 1 decimal place. Your Answer: Answer
A fireman uses a fire hose at an angle of 30 degrees above the horizontal and the water exits at 20 m/s. If the building is at a distance (d) of 40 meters and the fireman holds the nozzle 2 meters above the ground. Write the horizontal and vertical position equations of motion. DO NOT SOLVE. Hint: Use y = h.
An open water tank 80cm high, 120cm long, and 50cm wide is to be transported. The acceleration is along the width of the water tank. If the horizontal acceleration is 3m/s^2, solve the volume of water spilled if the tank is full prior to motion. O 0.046m^3 O 0.092m^3 0.220m^3 O 0.110m ^3
An open water tank 80cm high, 120cm long, and 50cm wide is to be transported. The acceleration is along the width of the water tank. If the horizontal acceleration is 3m/s^2, solve the initial volume of water such that no water will be spilled during motion. O 0.59m^3 O 0.43m^3 0.37m^3 0.69m^3
juice storage tank in a processing company was accidently hit by a stone from children playing nearby that caused leakage of the juice. If the top of the tank is open to the atmosphere and the level of juice is 350 cm above the hole, determine the speed at which the juice will leave the hole. Given that s.g. of juice is 1.054, g= 9.8 m/s2. State all assumptions made.
A city holding tank for water sits 21.0 above the city. If a house near the holding tank was on fire, to what height would firefighters have to drain the tank so water sprayed from the bottom of the tank hits the top of the house at its center, 10.0 m above the ground and 12.0 m away? QUESTION 2 Consider the water tank from the previous question. What is the speed (in m/s) of the water as it leaves the bottom of the tank? QUESTION 3 Assume the tank from the previous questions is sealed airtight with an air gap between the water's surface and the top of the tank. The air pressure in the air gap is 25.0 kPa, while atmospheric pressure outside the tank is 101.4 kPa. Assuming the velocity of the water level in the tank is effectively zero, to what height will firefighters now need to drain the tank so water hits the burning house? (Assume the density of the water is 1000 kg/m3. Report your answer to two decimal places.)
