Is the graph linear? Should it be? Why? Calculate what the value of the slope should be using your values from the above table in Eq. 1. Then perform a Linear Fit to your data in Excel. A box should appear indicating the slope of the graph. Record the slope in your notebook. Im confused with how to find the slope.   1st picture is the table where the values are 2nd picture is the equation 1

Question

Is the graph linear? Should it be? Why? Calculate what the value of the
slope should be using your values from the above table in Eq. 1. Then
perform a Linear Fit to your data in Excel. A box should appear indicating
the slope of the graph. Record the slope in your notebook.

Im confused with how to find the slope.

 

1st picture is the table where the values are

2nd picture is the equation 1

We can calculate the net force from the fluid acting on the object, which we call
the "Buoyant Force" (F3):
FB = Fpottom - Ftop = Prtuia 9 · A · (hz – h,) = Prtuia I · V (Eq.1)

PHYS 2LB: Lab 3
Buoyancy
where V = (h2 - h1)A is the volume of the fluid displaced by the object. This
buoyant force is equal and opposite to the force exerted on the displaced fluid by
gravity. Archimedes' Principle applies to all types of fluids (both liquids and gases).
Note that it also applies to floating objects, where Frop ~ 0. In today's lab you will
be studying how Archimedes' Principle applies to objects either fully submerged
in or floating on water.
