Answer:
True
Explanation:
Pauli exclusion principle states that in an atom, no two electrons have same set of the quantum numbers. The electrons in an atom have a unique set of quantum numbers ,
Even the electron is in same shell, same subshell and same orbital, the spin quantum number will be different for the two of them.
For example : 2 electrons in
n = 2 , l = 1 , m = 1 but s is different for both of them . (+1/2 or - 1/2)
<span>Na+/K+ ATPase (sodium pump) is considered to be an electrogenic pump because during every transport cycle, it transports 3 Na+ ions out of the cell and 2 K+ ions into the cell. This leads to the movement of one net positive charge out of the cell making this process electrogenic.</span>
The distance from the centre of the rule at which a 2N weight must be suspend from A is 29.3 cm.
<h3>Distance from the center of the meter rule</h3>
The distance from the centre of the rule at which a 2N weight must be suspend from A is calculated as follows;
-----------------------------------------------------------------
20 A (30 - x)↓ x ↓ 20 cm B 30 cm
2N 0.9N
Let the center of the meter rule = 50 cm
take moment about the center;
2(30 - x) + 0.9(x)(30 - x) = 0.9(20)
(30 - x)(2 + 0.9x) = 18
60 + 27x - 2x - 0.9x² = 18
60 + 25x - 0.9x² = 18
0.9x² - 25x - 42 = 0
x = 29.3 cm
Thus, the distance from the centre of the rule at which a 2N weight must be suspend from A is 29.3 cm.
