In the example, the final kinetic energy is determined to be ___________ because at the peak height, the ball instantaneously st
alina1380 [7]

TLDR: The kinetic energy is determined to be zero.

Kinetic energy is energy of motion; when an object is moving (i.e. it has speed or velocity), it has some amount of kinetic energy. The equation itself looks like so:

KE=1/2(m)(v)^2,

where "m" represents the mass of the object and "v" represents the objects speed or velocity. In this example, the ball has stopped, meaning it has no speed/velocity. This means that the final kinetic energy is determined to be zero or none, due to the lack of motion. Mathematically, you can see this by substituting "0" in for "v" (the ball is stopped):

KE=1/2(m)(v)^2

KE=1/2(m)(0)^2

KE=1/2(m)*0

KE=1/2*0

KE=0 J,

or zero kinetic energy.

Hope this helps! :)

What is the density of an object if it has a mass of 73 grams and a volume of 3.8cm3?
SashulF [63]

The density of the object is 19 g/cm³.

The mass of the object is 73 g.

The volume of the object is 3.8 cm³.

Density = mass/volume = 73 g/3.8 cm³ = 19 g/cm³

The proton number of barium (Ba) is 56. It is in Group II of the periidic table how many electrons would you expect a barium ato
ella [17]

Answer:

A barium atom would be expected to contain 2 electrons in its outer energy level.

Explanation:

The columns of the periodic table are called groups. There are eighteen groups, numbered from 1 to 18.

The elements of each group have the same number of electrons in their last atomic shell, which is why they have similar chemical properties, because the chemical properties of chemical elements are strongly related to the electrons located in the last atomic shell.

That is, in a group, the chemical properties are very similar, because all the elements of the group have the same number of electrons in their last or last shells.

<u><em>A barium atom would be expected to contain 2 electrons in its outer energy level.</em></u>
