A60.0-kg survivor of a cruise line disaster rests atop a block of styrofoam insulation, using it as a raft. the styrofoam has dimensions 2.00 m ✕ 2.00 m ✕ 0.0845 m. the bottom 0.023 m of the raft is submerged.(1) write newton's second law for the system in one dimension, using b for buoyancy, w for the weight of the survivor, and wr for the weight of the raft. (set a = 0. solve for fy, the y- component of the net force. let upward be positive y direction.
(2) calculate the numeric value for buoyancy. (seawater density = 1025 kg/m3.) 1004.5
(3) using the value from buoyancy and the weight of the survivor, calculate the wight of the styrofoam. 406.7
(4) what is the density of the styrofoam?
(5) what is the maxium buoyant force, corresponding to the raft being submerged up to its top surface?
(6) what total mass of survivors can the raft support?

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback

What is created when solids,liquids,an gases mix with one another

Which best describes how fluids change as they travel through different portions of the convection currents? they change to solids at the outer portion of the convection currents. they change to solids at the inner portion of the convection currents. they become more dense at the outer portion of the convection currents. they become more dense at the inner portion of the convection currents
