A digital rectal exam (DRE) is one of the primary methods a doctor uses to check your prostate. It involves the doctor briefly inserting a finger into your rectum to feel for potential abnormalities. The abnormalities may include symptoms associated with prostate cancer, benign prostate hyperplasia (an enlarged prostate), and prostatitis (an inflamed prostate usually from infection).
Lenz Law is a way to find the direction of induced current in a conducting loop. As per Faraday's Law of electromagnetic induction, a current is induced in a conducting loop by the changing magnetic flux. This induced current itself produces a magnetic field and hence a magnetic flux.
An animation showing the relationship between pressure and volume when amount and temperature are held constant. Boyle's law (sometimes referred to as the BoyleâMariotte law, or Mariotte's law) is an experimental gas law which describes how the pressure of a gas tends to decrease as the volume of a gas increases.he mathematical equation for Boyle's law is: where: 1  P denotes the pressure of the system. 2  V denotes the volume of the gas. 3  k is a constant value representative of the pressure and volume of the system.
