According to the Jefferson lab, "The scientific definition of work is: using a force to move an object a distance (when both the force and the motion of the object are in the same direction.)"
 
        
             
        
        
        
In both cases less energy is required
But comparetively Mg require more energy than K
Let's see the electron configuration of Both
- [Mg]=1s²2s²2p⁶3s²=[Ne]3s²
- [K]=1s²2s²2p⁶3s²3p⁶4s¹=[Ar]4s¹
K has only one valence electron so very less ionization enthalpy so less energy required
Mg has 2 so more IE hence more energy required
 
        
             
        
        
        
Answer:
The current across the resistance is 0.011 A. 
Explanation:
Total resistance, R = 25 ohms 
Total current, I = 100 mA = 0.1 A 
Let the voltage is V. 
By the Ohm's law 
V = I R 
V = 0.1 x 25 = 2.5 V 
Now the resistance is R' = 220 ohm 
As they are in parallel so the voltage is same. Let the current is I'. 
V = I' x R' 
2.5 = I' x 220 
I' = 0.011 A
 
        
             
        
        
        
Answer:
the force will decrease to 3/4 of its original value.
Explanation:
The initial electric force between the two charges is:

where
k is the Coulomb's constant
q is the magnitude of each charge
r is their separation
Later, half of one charge is transferred to the other charge; this means that one charge will have a charge of

while the other charge will be

So, the new force will be

So, the force will decrease to 3/4 of its original value.
 
        
             
        
        
        
Answer:
B
Explanation:
Absolute advantage is the capability of a commercial entity to produce goods using fewer resources compared to rivals. Using the same inputs, an entity with an absolute advantage produces a larger output compared to competitors. It means the firm has a lower marginal cost of production. Therefore, its products will have the lowest prices in the market.
