Wrinkles are caused by a combination of factors such as aging, reduction in collagen and elastin production, repeated facial expressions, sun exposure, and genetics. While older people tend to have more wrinkles due to these cumulative effects over time, younger individuals can also develop wrinkles prematurely due to lifestyle factors like smoking, poor diet, and excessive sun exposure.
The law of elasticity, or Hooke's law, was discovered by the British scientist Robert Hooke. It states that the stretching of a solid body is proportional to the force applied to it.
As buoyant force decreases then the body starts sinking down.
