The density is determined on the steepness of the slope. The greater the density is bases upon the steepest slope. To conclude, I'd say Line A has the steepest slope therefore has the greatest density.
It really depends on how far or close the planet is from the sun
Answer:
6.25×10^-11
Explanation:
The equilibrium charge = 2.4 - (2.3/2)
Equilibrium charge= 2.4 - 1.15= 1.25uc
Total charge= final charge - initial charge
Total charge= 1.25uc - 2.40uc= -1.15uc
Total charge transferred = -1.15 + 1.25 = 0.1uc
Number of electrons equivalent to 0.1uc= (0.1×10^-6)/-(1.6×10^-19)
Number of electrons = 6.25×10^-11 electrons
Answer:
In order to make this force twice as strong, F' = 2 F, the distance would have to be changed to half i.e. r' = r/2.
Explanation :
The electric force between two point charges is directly proportional to the product of charges and inversely proportional to the square of the distance between charges. It is given by :
r is the separation between charges
If F'= 2F
In order to make this force twice as strong, F' = 2 F, the distance would have to be changed to half i.e. . Hence, this is the required solution.
