You can also enter units that are combinations of other units. keep in mind that you have to indicate the multiplication of units explicitly either with a multiplication dot or a dash. you can add a multiplication dot by selecting the dot multiplication dot from the templates symbol menu menu. the weight of an object is the product of its mass, m, and the acceleration of gravity, g (where g=9.8 m/s2). if an object's mass is m=10. kg, what is its weight? express the weight with the appropriate units.
