When a truck pulls onto it, theboat sinks 4.00 cm in the water. What is the weight of the truck?4. An empty rubber balloon has a mass of 0.0120 kg. The balloon is filledwith helium at 0°C, 1 atm pressure, and a density of 0.179 kg/m. Thefilled balloon has a radius of 0,500 m.a. What is the magnitude of the buoyant force acting on the balloon?(Hint: See Table 1 for the density of air.)b. What is the magnitude of the net force acting on the balloon?
