Answer: Option (A) is the correct answer.
Explanation:
Since Robert has a history of depression this means that he is mostly worried about his image in his family and friends because everyone wants to look good in everybody's eyes.
Similarly, Robert also wants to be treated fairly well by everyone around him as he wants that everybody consider him normal.
Thus, Robert’s apprehension to get help is an example of a fear of being stigmatized.
From the solution that I have done, the wavelength in the question that we have is 31.88 cm
<h3>How to solve for the wavelength</h3>
The frequency in the question is given as 40/30 = 1.33 hz
Next we have to solve for V
= 425/10
= 42.5 cm/s
v = frequency * wavelength
we have to put in the values in the formula. This would be
42.5 = 1.33 x wavelength
we have to divide through by 1.33 to get the wavelength. This would be
42.5/1.333 = wavelength
31.88 cm = wavelength
Hence we can say that the wavelength in the question that we have here is 31.88 cm

The experiment's time period is unaffected by the change in amplitude in either experiment.
<h3>What are the variables that affect time in SHM?</h3>
The time frame is provided by:

where,
T = Time period.
M = mass.
k = spring constant.
We can see from the formula above that the only factors affecting the time period in a Simple Harmonic Motion (SHM) are the object's mass and spring constant. Any changes in the object's mass or the spring constant will cause the time period to adapt.
<h3>Describe the Spring Constant.</h3>
The attribute is known as a spring's "spring constant" describes the relationship between the force acting on a spring and the displacement it causes. In other terms, it describes the stiffness and size of a spring's range of motion.

Nuclear fusion reaction is mainly responsible for the cause of energy radiation from the sun.
Solar energy is created due to this nuclear fusion. The discharge of energy in the sun is 10²⁶ joules per second
There is nuclear fusion of hydrogen into helium molecules.
Takes place in solar nucleus.
The type of fusion in nuclear fusion is proton-proton fusion. The 2 condition which help H-H atoms come together is large mass of the sun and the force of gravity
