An empty 18.00 x 9.000 x 2.500 barge is floats in Conception Bay (ρ = 1,023 kg/m³).

a) Calculate to what depth the empty barge is submerged when it floats, given its empty weight is 2,940 kN.

b) Calculate the mass of additional grabage that may be added to the barge such that it is on the verge of sinking, in a calm body of water.

a. An astronaut holding a heavy object floats in empty space. When he throws the object, he finds himself moving in the opposite direction. Explain, using conservation of momentum, why this occurs. b. A system starts with a net momentum of zero and is only affected by internal forces. After a series of events, what must the net momentum of the system be? If the forces are external, why is this not necessarily the case? c.A box slides along ice...

Prove that step by step and clear handwritten. Follow the comment Conception: Limit point 1.Prove N'=empty 2.Prove Q'=R 3. E=(2,5), E'=[2,5] my question is that why the collection limit point of E includes 2 and 5? obviously, 2 and 5 are not in E. If they can be limit point in E does that mean R can be all set's collection of all limit point? such as R'=R, Q'=R, N'=R???
