2. ### A spring hangs from a support, at rest. If you suspend a 0.46kg mass from it, its deflection is 7.9cm.?

the equation: k = – F/x. Where k is the spring constant, F is the force applied over x, and x is the displacement by the spring F =mg Subbing in we get k = mg/x N/m So make sure to convert cm to m

The pressure at the level of the bottom of the "liquid of density ρ" is the same on both sides of the apparatus. pressure = ρgh and so on the left side we have p = ρ*g*(d+ℓ) and on the right side p = ρw*g*2ℓ equating the two and canceling g we get ρ*(d+ℓ) = ρw...
