Final answer:
Cadavers have a weight determined by their mass, but from a visual perspective, they may not always appear as heavy as they actually are due to factors like posture, muscle tone, and clothing.
Step-by-step explanation:
The question is asking whether cadavers are heavier than they seem. In physics, weight is the force exerted by an object due to gravity. So, the weight of an object depends on the mass of the object and the acceleration due to gravity. Cadavers, like any other object, have a weight determined by their mass, but from a visual perspective, they may not always appear as heavy as they actually are due to factors like posture, muscle tone, and clothing.
