- PLEASE SEND THE ANSWER IN 5 MINUTES !!! Suppose that you plot the mass (y-axis, in g) versus volume (x-axis, in cm3) of 4 different geometrical objects on a graph paper. When you plot, you see that 3 of the objects seem to line up. Then, for the best fit line to these 3 objects, assume that you get the following slope points: Slope point 1 : (1;1.1) Slope point 2 : (11;28.5) Using these slope points, calculate the density of these 3 objects in units of g/cm .Give Your answer with 3 significant figures.arrow_forwardAn astronaut has a mass of 120 kg.
