Answer:
Explanation:
First, we are going to calculate the electrical potential in the point middle between the two charges
Remember that the electrical potential can be calculated as:
Where 
and it is satisfy the superposition principle, thus
The electrical potential at 10 cm from charge 1 is:
Since the work - energy theorem, we have:
where q is the electron's charge and m is the electron's mass
Therefore:
Answer:
q=6.22*10^-10C
Explanation:
Two large metal plates of area 0.88 m2 face each other, 4.8 cm apart, with equal charge magnitudes but opposite signs. The field magnitude E between them (neglect fringing) is 80 N/C. Find |q|
E=α/∈, electric field within the plate
α=q/A
A=area of the plate
∈=is the permittivity
substituting , we have
The field magnitude E between them (neglect fringing)
E=q/A∈
q=EA∈
q=0.88*80*8.84*10^-12
q=6.22*10^-10C
The baseball because it has a greater mass and would go farther because it don't have holes for the air to go through and slow it down
The given reaction is an exothermic reaction due to the negative amount of enthalpy. In this case, an increase in temperature favors the backward reaction which points to the creation of more products. The expression of K or Q is products over reactants concentration. When this happens, Q becomes smaller then. Hence answer is C and 1.
