Question: 1. Refer to MultipleConcept Example 11 to see a problem similar to this one. What is the smallest number of whole logs {p = 725

Refer to MultipleConcept Example 11 to see a problem similar to this one. What is the smallest number of whole logs {p = 725 kgfms, radius = 0.0846 m_. length = 2.90 m} that can be used to build a raft that will carry four people, each of whom has a mass of 70.0 kg? A hot-air balloon is accelerating upward under the influence of two forces, its weight and the buoyant force. For simplicity, consider the weight to be only that of the hot air within the balloon, thus ignoring the balloon fabric and the basket. The hot air inside the balloon has a density of Phot air = 0.77 kg/m", and the density of the cool air outside is Pcool air = 1.29 kg/m . What is the acceleration of the rising balloon?Water flows straight down from an open faucet. The cross-sectional area of the faucet is 1.1 x 10-4m and the speed of the water is 0.70 m/s as it leaves the faucet. Ignoring air resistance, find the cross-sectional area of the water stream at a point 0.12 m below the faucet
