They make interference waves
I don't know what the tables you have look like but her <span>displacement</span> would be -1m
Since the mirror is plane, the image will be formed behind the mirror. The distance will be the same as that of the distance of the object from the mirror and the height will just be the same.
So, Ruff's image will be 3 m behind the mirror and 50 cm tall.
Answer:
Distance,
Explanation:
It is given that,
Charge,
Area of the parallel plate capacitor,
We need to find the distance between the plates. Let it is equal to d. The capacitance of the parallel plates capacitor is given by :
k = relative permittivity, for air k = 1
So, the distance between plates is . Hence, this is the required solution.
