Answer:
The charge stored is
The energy stored is
Explanation:
From the question we are told that
The area of the plates is
The separation between the plate is
The potential difference is
The permitivity of free space is
The dielectric constant of glass is K = 5.0
Generally the capacitance of this capacitor is
substituting values
The charge stored is mathematically evaluated as
substituting values
The energy stored is
substituting values
To solve this problem we will apply the principles of conservation of energy, for which we have to preserve the initial kinetic energy as elastic potential energy at the end of the movement. If said equality is maintained then we can affirm that,
Here,
m = mass
k = Spring constant
x = Displacement
v = Velocity
Rearranging to find the velocity,
Our values are,
Replacing our values we have,
Therefore the velocity is
Answer:
Explanation:
Note that acceleration is the rate change of velocity i.e
.
Since the velocity is giving as a variable dependent on the pressure, we have to differentiate implicitly both side with respect to time,i.e
if we substitute value for the pressure as giving in the question and also since the rate change of pressure is 0.354psi/sec, we have
