In the study of physics, Hooke's law can be expressed as:
F = kx
This law indicates that the spring force F is proportional to the extension x, with k being the spring constant.
In experiments, this is often examined using the setup illustrated in the included figure. The spring is tested, and a known weight is applied underneath it. This weight exerts a gravitational pull, essentially its weight, on the spring. While the spring elongates, the displacement can be measured using a ruler.
Several potential errors can arise during this experiment. Firstly, the person's measurement reading may be faulty. Digital scales offer greater accuracy as they reduce human error, while ruler readings can be subjective, especially if not viewed at eye level. Additionally, the object's weight may be inaccurately measured if the scale is untrustworthy. Lastly, the measuring equipment may not be correctly calibrated.
To address this problem, Boyle's Law must be applied, which states that the initial and final pressures and volumes are related as follows: Where, P₀ and V₀ represent the initial pressure and volume, while P and V refer to the final pressure and volume. The endpoint pressure in this scenario is atmospheric pressure. Thus, using the given equation, we can find the volume the lungs would occupy at the surface.
Response:
D: The distance among the particles diminishes
Clarification:
Removing energy reduces the activity of molecules, similar to how one slows down in cold temperatures (I believe).
Answer:

Explanation:
Consider the following:
Length= 2L
Linear charge density=λ
Distance= d
K=1/(4πε)
The electric field measured at point P



Thus,

Now, by applying integration to the equation above

Answer:
The third-order dark fringe
Explanation:
y = Distance from central bright fringe = 204 mm
λ = Wavelength = 400 nm
L = Distance from screen to source = 1 m
d = Slit spacing = 6 μm


The order of the fringe is 3
Thus, it’s identified as a dark fringe.
