Answer: Option (e) is the correct answer.
Explanation:
There are three types of kinetic energy which are vibrational, rotational and translational kinetic energy.
A plucked string on a guitar will produce sound and it represents vibrational kinetic energy.
The moving blades of a ceiling fan shows the rotation of blades and it represents rotational kinetic energy.
A spinning top also displays rotation therefore, it represents rotational kinetic energy.
A tuning fork struck on a rubber block will produce sound and it will vibrate. Therefore, it represents vibrational kinetic energy.
An apple falling from a tree shows that apple is linearly falls on the ground therefore, it represents translational kinetic energy.
Thus, we can conclude that an apple falling from a tree is the best example which represents translational kinetic energy.
They would most likely use statistics on the increase/decrease in population from previous decades and centuries. In addition to these statistics, they could use the birth and death rate and ultimately predict the increase within these next 30 years. They must also take climate change and other environmental factors into consideration when formulating such a bold prediction.
Answer:
The bigger the atom the lesser the ability of the atom to hold on to its valence electrons.
Explanation:
Atomic radius can be looked at as the distance between the nucleus and the outermost energy level. As an atom gets bigger, the outer shell gets further and further from the positive nucleus. this means that electrons that are in the outer energy level become less held (attracted) by the nucleus because of distance and shielding of the attractive forces by the electrons in the lower energy levels. This means that as an atom becomes bigger, its ability to hold on to its outer electrons lessens.
