A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
In an experiment to determine the figure of merit of a galvanometer by half deflection method, a student constructed the following circuit. He applied a resistance of \( 520 \, \Omega \) in \( R \). When \( K_1 \) is closed and \( K_2 \) is open, the deflection observed in the galvanometer is 20 div. When \( K_1 \) is also closed and a resistance of \( 90 \, \Omega \) is removed in \( S \), the deflection becomes 13 div. The resistance of galvanometer is nearly:
Any adverse variation from an organism's normal structural or functional condition is usually associated with specific signs and symptoms and distinct from physical injury.
A few diseases appear out of nowhere and persist only a few days. Acute diseases, such as the common cold, are examples of them. Acute diseases frequently become chronic if they are not treated.
Acute diseases include strep throat, fractured bones, appendicitis, influenza, pneumonia, and others.
Acute diseases develop quickly and are accompanied by unique symptoms that necessitate immediate or short-term treatment and improve once treated. Acute illnesses, such as the common cold, can sometimes go away on their own.
Chronic diseases are illnesses that develop over time and endure for a long time or even a lifetime. Chronic disease is defined as a disease that lasts more than three years. The symptoms are relatively modest at first.
