A team of engineering students is testing their newly designed 200 kg practices. The raft must hold a 730 kg steel cube with edges of length 45.0 cm density of water in the pool is 1000 kg/m raft in the pool where the diving team Assume the without sinking. 

a. The students use a crane to gently place the cube on the raft but accidentally place it off center. he cu remains on the raft for a few moments and bottom of the pool. The raft remains floating in the pool. In a coherent paragrap whether the water level in the pool when the cube is on the bottom of the pool is higher than, lower thano the same as when the cube is on the raft, and explain your reasoning. For both cases, assume that therezs.n motion of the water. then the raft tilts, causing the cube to slide off and sink to the h-length response, indicate 

(b) The bottom of the pool is 5 m below the surface of the nt specd. so the pool. The cube is lifted upward at a slow and forces are negligible. the surface of the water. The crane is now used to lift the of 4.0 m. Ees to the force eton the cube when the bottom of the cube is at a m compares to the force exerted by the crane on of 4.0 m. Explain your reasoning bosto ortom of the cube is at a depth cube septh.

i. Predict how the force exerted by the crane on thc on dhe cube w your reasoning.by the On the black squlan bih sanpesents the cube, draw and label the forces (not below the surface are exerted on the waer ach force must be represented by a distinct arrow starting on, and pointing away froim square. The lengths of the arrows should approximately demonstrate the net force on the fn the cube while the crane is lifting it and the bottom of the cube is 4 m below the strec cue cube. 

 

ii. Calculate the force exerted by the crane on the cübe when the bottom of the cube is 4 m below the surface of the water.
