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.

Explanation:

Archimedes principle states that the upward buoyant foce exrted on a body is equal to th wight o the liquid displaced.

Now, the buoyant force on the boat is given by:

is the volum is the density is the mass of the boat and is the mass added to the boat.

is the surface area and is the depth.

The equation for thebest fit linis,

Re-arrangethis equati for

From equations(1) and (2),

the density is,

Therefore, the density of the liquid is

wavelength divides in half and speed stays the same.

what is the actual question though?
