Answer:
12500 V
Explanation:
The electric field in the gap of a parallel-plate capacitor is uniform, so the following relationship between electric field strength, potential difference and distance can be used:

where
is the potential difference between the plates
E is the electric field strength
d is the distance between the plates
For the capacitor in this problem, we have


Substituting, we find

Answer:
0.80 m
Explanation:
elastic potential energy formula
elastic potential energy = 0.5 × spring constant × (extension) 2
Answer:
Explanation:
Correct order of energy of energy states within an atom is as follows
1s , 2 s, 2 p 3 s ,3 p, 4s , 3d, 4p, 4p,5s etc.
There is discrepancies in this order due to overlapping of outer orbitals with inner orbitals so sometimes outer orbitals have lower energy.
Vf = Final velocity.
Vi = initial velocity
a = acceleration.
t = time
Vf = Vi + at
Vf = 0 + (2 m/s^2)(3s)
Vf = 6 m/s south
Answer:
Energy will be
Explanation:
We have given that dielectric constant k = 5
Area of the plate 
Distance between the plates 
Electric field E = 200 kN/C
We know that capacitance is given by 
We know that electric field is given by 
So 
So energy will be
