Answer:
Part a)
Part b)
Explanation:
As we know that the energy of capacitor when it is not connected to potential source is given as
As we know that initial energy is given as
now we know that capacitance of parallel plate capacitor is given as
now the new capacitance when distance is changed from 3.80 mm to 1.45 mm
Now the new energy of the capacitor is given as
Part b)
Now if the voltage difference between the plates of capacitor is given constant
now the energy energy of capacitor is
now when capacitance is changed to new value then new energy is given as
Long time ago, people saw the constellations as patterns in the sky. They names these patterns and tell stories about them. What people saw laong time ago are just mere patterns which forms animals and shapes. We got the names of our constellations from the Greeks who named the constellations after the mythological heroes and mythological legends.
Answer:
3 m/s squared
Explanation:
The formula you use is Vf= Vi + at. You rearrange it to a= Vf - Vi/t. The Vf is 27m/s. The Vi is 0m/s and the t is 9s. Cross out Vi since it’s zero and you’re left with a= 27m/s divided by 9s, which equals 3
When an atom becomes electrically charged the number of electrons or protons stops and they are not equal again. The "extra" electron or proton is not balanced by something inside the atom any longer and it starts attracting itself to othet protons or electrons in other atoms.
<h3>What is atomic structure?</h3>
An atomic structure comprises of positively charged nucleus which is surrounded by negatively charged particles called electron and neutron which is neutral charged.
Unlike charges attract each other while like charges repel each other.
Therefore, When an electron is fully charged, the number of electrons will stop to be unequal again.
