A student measures the mass 8cm block of brown sugar to be 12.9g. what is the density of the brown sugar.

0.025g/cm³

Explanation:

let us assume that the length is 8cm since it is not clearly given.

Given parameters:

Mass of the cube sugar = 12.9g

length of the sugar  = 8cm

Unknown:

Density of the brown sugar  = ?

Solution:

Density is the mass per unit volume of a body. It is given as;

            Density  =

Volume of the cube sugar  = l³

                                             = 8³

                                              = 512cm³

Input the parameters;

                 Density  =   = 0.025g/cm³

scientific laws are the result of testing theories and proving them to be facts.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
