Sheena wants to measure the volume of a ball that is 24 cm across. How should she set up her equation?

the answers would be

the first one and the second one

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
