When your pushing or pulling things, you can use your strength, or Muscles to use a force on any object.
Hope this helps :).
Answer: Option (D) is the correct answer.
Explanation:
Non-metals are electron deficient in nature so, in order to complete their octet they need to gain electrons from metals or electron rich atoms.
Whereas metals are electron rich in nature so, in order to gain stability metals lose their valence electrons.
For example, atomic number of potassium is 19 and its electronic distribution is 2, 8, 8, 1. Whereas atomic number of chlorine is 17 and its electronic distribution is 2, 8, 7.
Therefore, sodium in order to gain stability will lose its valence electron to chlorine atom. Hence, an ionic bond will be formed resulting in the formation of KCl.
Thus, we can conclude that non-metals seek to gain electrons to have full outermost shells, while metals seek to lose electrons to have full outermost shells.
They are made by the wind. ^-^
Each ring marks an entire cycle of seasons, or one year, within the tree's life. Hence 23 rings shows 23 years of trees life . Measurement of tree rings are based on Radiocarbon dating. These rings can tell us how old the tree is, and what the weather was like during each year of the tree's life. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall.
Rings of trees growing in temperate climates can indeed tell their age through their annual rings and also help determine the age of wood used to construct buildings or wooden objects.
