Hey...
➡ Simple Pendulum - It is a device in which heavy point mass (Bob) is suspended by an Inextensible thread from a fixed support and is allowed to swing freely under the influence of gravity. In simple pendulum, to and fro motion of same length are of the same duration of time.
➡ Batter - It is a combination of two or more cells. In a batter, the positive terminal of one cells is connected to the negative terminal of the next cell.
➡ Compound Microscopic - It is used for viewing the microscopic objects or organism which are not seen by the naked eyes.
➡ Cover Slip - It is acchi square or round glass piece used to cover specimen kept on the slide. It avoids the contact of the specimen with lens of microscope.
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position...
