Complete question is;
Three grams of the same substance in different phases are stored in three different containers. Each container is barely large enough to hold the substance. Which statement can be known about the behavior of the atoms in each container?
A) The atoms in the solid would be moving vigorously around the container.
B) The atoms in the liquid would be vibrating in position.
C) The atoms in the solid would be vibrating in position.
D) The atoms in the gas would be moving slowly around the container.
Answer:
Option C - The atoms in the solid would be vibrating in position
Explanation:
Option A is wrong because the molecules in solids are held together by strong inter molecular forces and therefore can't move about freely but instead will vibrate in their position.
Option B is wrong because the atoms in liquid are more free than those in solids. Thus they will not have room to vibrate.
Option C is correct from the explanation from option A.
Option D is wrong because the atom of the gas would be very loose and free and would therefore be moving very fast around the container
Answer:
1.625 Pounds Explanation:
The potential energy is most often referred to as the "energy at rest" and is dependent on the elevation of an object. This can be calculated through the equation,
E = mgh
where E is the potential energy, m is the mass, g is the acceleration due to gravity, and h is the height. In this item, we are not given with the mass of the cart so we assume it to be m. The force is therefore,
E = m(9.8 m/s²)(0.5 m) = 4.9m
Hence, the potential energy is equal to 4.9m.
