<span>a number assigned to an element in a chemical combo that represents the number of electrons lost or gained by atom of the element in the compound.</span>
Power is the energy transferred or "WORK DONE" in one second
Answer:
Explanation:
Mechanical Advantage is the ratio of the distance of the input load (Li)from the pivot to the output load applied to the pivot(Lo)
MA = Li/Le
Given;
Li = 45cm
Lo = 1.8cm
MA = 45/1.8
MA = 25
Hence the mechanical advantage is 25
Also MA is expressed in terms of the force ratio which is the ratio of the Load to the effort applied.
MA = Load/Effort
Given
Load = 1250N
MA = 25
Effort = ?
Substitute
25 = 1250/Effort
Effort = 1250/25
Effort = 50N
Hence the minimum force exerted on the load is 50N
Explanation:
The given data is as follows.
![U_{a} = 5.4 \times 10^{-8} J](https://tex.z-dn.net/?f=U_%7Ba%7D%20%3D%205.4%20%5Ctimes%2010%5E%7B-8%7D%20J)
![W_{/text{a to b}} = -1.9 \times 10^{-8} J](https://tex.z-dn.net/?f=W_%7B%2Ftext%7Ba%20to%20b%7D%7D%20%3D%20-1.9%20%5Ctimes%2010%5E%7B-8%7D%20J)
Electric potential energy (
) = ?
Formula to calculate electric potential energy is as follows.
= ![5.4 \times 10^{-8} J - (-1.9 \times 10^{-8} J)](https://tex.z-dn.net/?f=5.4%20%5Ctimes%2010%5E%7B-8%7D%20J%20-%20%28-1.9%20%5Ctimes%2010%5E%7B-8%7D%20J%29)
= ![7.3 \times 10^{-8} J](https://tex.z-dn.net/?f=7.3%20%5Ctimes%2010%5E%7B-8%7D%20J)
Thus, we can conclude that the electric potential energy of the pair of charges when the second charge is at point b is
.
