Question
**Educational Content: Calculating Initial Mass Flow of Air in a Balloon** ### Problem Statement: The balloon has a mass of 15 grams (empty) and is filled with air at a temperature of 20°C, with a density of 1.202 kg/m³. When released, the balloon accelerates upward at 8 m/s². ### Objective: Determine the initial mass flow of air from the stem. Assume the balloon is a sphere with a radius of 200 mm. Express the answer using three significant figures. ### Diagram Explanation: The image depicts a spherical balloon with an upward acceleration of 8 m/s². The radius of the sphere is given as 200 mm. The stem through which the air flows out has a diameter of 5 mm. ### Task: - Use the given physical properties and conditions to calculate the initial mass flow rate of air. - Ensure the calculations are precise, providing the answer in grams per second (g/s). ### Calculation Space: A formula box is provided to input the calculated answer, alongside a submission button. Four attempts are available to input the correct values. ### Feedback: It is possible to review previous answers or request help if needed. Any incorrect answer will be marked, and attempts will be deducted. ### Instructions: Think critically about the forces involved, apply relevant physics equations, and remember to convert units when necessary to obtain the correct mass flow rate.
