Answer:
The uncertainty in the location that must be tolerated is
Explanation:
From the uncertainty Principle,
Δ Δ
The momentum P = (mass of electron)(speed of electron)
=
=
If the uncertainty is reduced to a 0.0010%, then momentum
=
Thus the uncertainty in the position would be:
Δ
Δ
Answer:
The correct option is H
Explanation:
From the question we are told that
The index of refraction of coating is
The index of refraction of material is
Generally the condition for constructive for a thin film interference is mathematically represented
Here t represents the thickness
For minimum thickness m = 0
So
=>
Here the block has two work done on it
1. Work done by gravity
2. Work done by friction force
So here it start from height "h" and then again raise to height hA after compressing the spring
So work done by the gravity is given as
Now work done by the friction force is to be calculated by finding total path length because friction force is a non conservative force and its work depends on total path
Total work done on it
So answer will be
None of these
