- A flat-bottomed aluminum fishing boat has a mass of 60 kg and an area of 4.0 m2. When it is launched into the water (density 1,000 kg/m3), how far (in m) below the surface of the water does the bottom of the boat sink?6. Please help answer this question, thank you so much!! :)A cylinder that is h1=18.0 cm tall and open on top is filled with water. If a hole is made in the side of the cylinder, Δh=3.90 cm below the top level, how far x from the base of the cylinder will the stream land? Assume that the cylinder is large enough so that the level of the water in the cylinder does not drop significantly.
- Apply error propagation to determine the associated uncertainty in the average volume… PlzA glass container weighing 4 N has of water and a 1 N block of styrofoam (100 kg/m3) that is held underwater by a rope. The rope is cut. 1. What is the acceleration of the block? (ignore friction). 2. What happens to the water level?Will the force exerted on the bottom of the tube increase if the diameter (d) of the tube increases and the height of the water column is maintained? 2. Since P = F/A, will increasing the weight of the water in the tube affect the pressure exerted on the bottom of the tube?
