harmonic mean h.m.

Harmonic Mean (H.M.) - If three quantities are in harmonic progression, then the middle quantity is called the harmonic mean between the other two. Example: 1/3, 1/7, 1/11 are in H.P., then 1/7 is the middle term. Hence 1/7 is th..

The restoring force in a spring (or in general, any elastic body) obeys Hooke's law. An English scientist Robert Hooke, in the year 1679, enunciated the fundamental law of elasticity in the form ut tensio sic vis which means, As the tension, so is the extension. Within the elastic limits,..

A car travels a distance of first 15 miles at a speed of 15 mph, next 15 miles at 30 mph and another 15 miles at 45 mph. Find the arithmetic mean and harmonic mean of these 3 speeds. Which is the correct measure of average speed? => 2 mph, 24.55 mph, harmonic..

Oscillatory motion or harmonic motion is a type of motion in which the to and fro motion of the object repeats itself at regular intervals of time about the mean position. Simple Pendulum consists of a heavy mass (spherical in shape) suspended by a long, inextensible and fl..
