Explanation:
let vertical distance from A to C be 
the constraint equation is:
we want to find 
distance can be written as 
which we will find by using Pythagorean theorem h 1 is a constant and can be written as h:
taking derivative w.r.t time we get
given 
which gives us
Answer:
It is Conductivity because it is the measure of the ease.
Answer:
When you increase speed, you add energy and increase momentum as it would require more energy to change, stop or reverse the object's direction of travel than before the speed increase. Increasing the speed increases the momentum proportionally.
Explanation:
Answer: Option (D) is the correct answer.
Explanation:
The given elements Li, C and F are all second period elements. So, when we move from left to right across a period then there occurs increase in number of valence electrons as there occurs increase in total number of electrons.
So, it means more electrons are added to the same energy level.
Thus, we can conclude that a property of valence electrons for each element is located in the same energy level is common in the given elements.
