1. A boy was travelling with her parents by means of water transport. He carried a ball and a phone taking selfies along the journey. On their way water waves disturbed the boat and all he had on his hands dropped in water. However, with much disappointment of losing his phone, all over sudden he realised the ball was still on top of water though phone was nowhere to be seen. This scene left them wondering the magic with the ball. As they continued, they looked in the air and saw two people seated in a bucket connected to a balloon with burning flame was carrying them in space. The boy was confused and wondered how the two men would land safely on the ground though his parents couldn't explain anything to him. Take the density of water =1000 kg/m³ Acceleration due to gravity = 10 ms² Mass of the boat Mass of a phone Volume of a phone Volume of a ball Volume of the boat = : 200 kg = 500 g = 50 cm³ = 20 cm³ = 3000 cm³ = As a Physics learner, help the boy understand what happened while on the boat and also explain for him how the two heavy men were being carried by just a balloon with burning air.
