Aplastic boat with a 25 cm² square cross section floats in a liquid. one by one, you place 50-g masses inside the boat and measure how far the boat extends below the surface.
your data are as follows:
mass added, m(g) - depth, d(cm)
50 - 2.9
100 - 5.0
150 - 6.6
200 - 8.6
graphing either m versus d or d versus m gives a straight line. in the graph shown above, we chose to plot d on the vertical axis and m on the horizontal axis. from the equation for the line of best fit given, determine the density rho of the liquid.
explain.

Which best represents the law of conservation of mass ?

The a992 steel rod bc has a diameter of 50 mm and is used as a strut to support the beam. determine the maximum intensity w of the uniform distributed load that can be applied to the beam without risk of causing the strut to buckle. take f.s. = 2 against bucklin

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
