A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
The current passing through the battery in the given circuit, is:
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
A naturally occurring process that occurs without any human input is known as Natural Phenomena. For instance, weather, gravity, fog, erosion, thunder, tides, biological processes, oscillation, etc. Winds, storms, and cyclones are some examples of natural phenomena. These are phenomena of destruction. Two other destructive natural phenomena are also discussed below:
