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
Answer:
Before the plank will tip cat will walk 1.652 m
Explanation:
Mass of the cat along with plank
Center of mass of the plank
Mass of cat
We have to find how far right of sawhorse B.
Plank will tip when weight of the cat about B is greater than the torque by the weight of the plank.
Balancing the the torque
