Answer:
The flow speed at 2.6 cm diameter pipe is 1.2
Explanation:
Given :
Speed at 4 cm diameter pipe
Area of 4 cm diameter pipe
Area of 2.6 cm diameter pipe
From the equation of continuity,
Find the speed at 2.6 cm diameter pipe,
Therefore, the flow speed at 2.6 cm diameter pipe is 1.2
Answer: third option: <span>have a full outer electron shell.
Explanation:
Noble gases is the family name given to the elements of group 18 of the periodic table.
The electron valence shell of all these elements is full:
He has two electrons wich is the maximum an atom of the first row can have.
Ne, Ar, Kr, Xe, and Rn (well you can include Og which is the last noble gas discovered; it is the element number 118), have 8 electrons on their valence electron shell, which is the maximum any element can have.
Precisely, that feature (valence shell full) accounts for the low reactivity of these elements, which conferred them the title of nobles (they hardly combine with other elements to form compounds).

For the speed of an object you need to know how far it is travelling in a given time. Typically you do this by measuring the time it takes for the object to travel a set distance.
<span>For the velocity of an object you also need to know the direction the object is travelling in.

I believe it is henry Moseley he designed it in 1900
Answer:
1600 N
Explanation:
pascals principle says..
so lets do
so multiply one half (2/4 simplified) by 3200
1600 is equal to x
1600 N
YAAAAAAAAAAAAAAY
