Which has more gravitational potential energy—a book sitting on a desk or the same
nydimaria [60]

Answer:

The book sitting on the desk

Explanation:

The gravitational potential energy of an object is the energy possessed by the object due to its position relative to the ground.

It is calculated as:

GPE=mgh

where

m is the mass of the object

g is the acceleration due to gravity

h is the height of the object with respect to the ground

From the formula, we see that the GPE of an object is directly proportional to the heigth h: so, the higher the location of the object, the larger the GPE.

In this problem, we are comparing a book sitting on a desk and the same book sitting on the floor. In the two situations, the mass of the book is the same; however, in the first case, the value of the height is h, while in the second case, the value of h is lower (because the book is located at a lower height, being on the floor).

Therefore, we can conclude that the first book must have a larger GPE, since it has a larger value of h.

Given the following equation: 2 K3N ---&gt; 6 K + N2 How many moles of N2 can be produced by letting 12.00 moles of K3N react?
myrzilka [38]
The answer will be 12 nitrogen or N2 will be produced because if you changed the coefficient to 12 on the reactant side and distribute, the nitrogen would be 12 when distributed and what happens on one side has to equal to the other side, which is the product side.

Why the statement all atoms of one element have the same mass is false
White raven [17]
Some elements have isotopes which have a different number of neutrons, and this means they have different masses.
