The spring's work output while it is not extended is 5 J.
<h3>What is The Hooke's law ?</h3>
According to Hooke's law, as long as the elastic limit is not exceeded, the extension of a particular material is directly proportional to the force applied. Hence, we must be aware of that F = Ke
F = Applied force
Force constant is K.
Extension = e
F = applied force
Force constant is K.
Extension = e
Using the graph
K = F/e
F = 200N
E equals 5 cm or 5 * 10-2 m
K = 200N/ 5 * 10^-2 m
K = 4000 N/m
Now;
Work = 1/2Ke^2
Work = 0.5 * 4000 N/m * (5 * 10^-2 m)^2
Work = 5 J

I think it's (26.coal)(25.wind.) I hope it's right.
the smallest possible piece of electromagnetic radiation:
-waves
-photons
-rays
Answer:
A
B
Explanation:
From the question we are told that
The wavelength is
The angle of first bright fringe is
The order of the fringe considered is n =1
Generally the condition for constructive interference is
=>
=>
Converting to cm
Generally the number of grating pre centimeter is mathematically represented as
=>
=>
Considering question B
From the question we are told that
The first wavelength is
The second wavelength is
The order of the fringe is
The grating is
Generally the slit width is mathematically represented as
=>
=>
Generally the condition for constructive interference for the first ray is mathematically represented as
=>
=>
=>
Generally the condition for constructive interference for the second ray is mathematically represented as
=>
=>
=>
Generally the angular separation is mathematically represented as

Gestalt psychology is a a theory of mind of the Berlin School of experimental psychology. It tries to understand the laws of our ability to acquire and maintain meaningful perceptions in an apparently chaotic world. It proposes that the whole of an object or scene is more important than its individual parts.
