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.
The ideal gas law is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions, although it has several limitations. It was first stated by Ãmile Clapeyron in 1834 as a combination of the empirical Boyle's law, Charles' law and Avogadro's Law.
