suppose, x = total length of the lotus stem 16 = exposed part of stem 56 = horizontal displacement. Hence the depth of water = x-16cm Using the Pythagorean theorem, (x-16)^2 + 56^2 = x^2 or, x^2 -32x + 256 +3136 = x^2 or, 3392 = 32x so x = 3392/32 = 106 Depth of water = x-16 = 106 – 16 = 90cm.
Shunt is a low resistance connected parallel to a device in an electric circuit. It is important because it provides bypass to large current which might otherwise damage the device.
