Help me plz !!!! A cat that weighs 55 N sits on the top of a cat tree. It is 2 m above a 110 N
weeeeeb [17]

Answer:

B. The 55 N cat has less mass than the 110 N dog.

Explanation:

Weight of an object refers to the product of its mass and the force of gravity. However, the greater that mass of an object, the greater the weight of that object.

In this case, the cat's weight is 55N while the dog's weight is 110N. This means that the dog has a greater mass than the cat or alternatively put, the 55 N cat has less mass than the 110 N dog.

Note that: if the gravitational effect is removed, the cat will contain lesser mass.

The mind provides assistance for this in the form of strong core education. Each nurse will have distinct talents, passions, and expertise because of the wide variety of specializations and complicated abilities required in the nursing practice.
