You would convert the cg to g. 1.66 cg is 0.0166 g. then you add. 0.398 + 0.0166 = 0.4146. the answer is 0.4146 grams.
Answer:
The easiest way is to heat matter which raises its internal energy andso the mass as well. Another possibility is to accelerate matter as in case of protons or heavy ions in the LHC, Protons ,for example , are accelerated to the energies of 6500 GeV which means increase of the rest mass by a factor of almost 7000
B.) Digestion
when food passes through the gastrointestinal tract, the food get mixed with digestive juices which break down large food molecules. The body absorbs these molecules/nutrients through the small intestine and enter your blood stream. Your blood stream delivers these nutrients to the rest of the body.
