Forces Acting on the Bob of a Simple Pendulum - The bob of a simple pendulum is attached to a string which pulls the bob along its lengt..

Tanya was reading a novel, which had 10 chapters. She spent 1 hour(s) reading the first chapter and took the same amount of time to read all the other chapters of the novel. She completed reading the novel in 19 hours. Solve the equation 1 + 9 h = 19, to find h , the n..

Two forces of 42 lb and 34 lb act on a body and the resultant force is 52 lb. Find the measure of the angle between the two forces. => 94°20′ or 85°40′ or 28°32′ or 62°28′..

The product of a + b and a 2 - ab + b 2 is a 3 + b 3 . Hence when a 3 + b 3 is factorised, we get: a 3 + b 3 = (a + b) (a 2 - ab + b 2 ) Similarly, a 3 - b 3 = (a - b) (a 2 + ab + b 2 ) Factorise: x 3 + 8 x 3 + 8 = (x) 3 +..

Two forces F 1 = 35 N and F 2 = 84 N act on a body at right angles. Find the resultant force. => 119 N or 76.3 N or 91 N or 49 N..

If two or more forces act on the same body, then the acceleration of the body can be written as the vector sum of the individual accelerations produced by each force. The acceleration of the body can be better expressed as the acceleration caused by the resultant for..

If a force acts on a particle P, then the torque acting on the particle with respect to the origin O is given by where gives the position of the particle with reference to the origin O. If both and lie in the XY plane the..

Two forces F 1 = 49 lb and F 2 = 39 lb act on a body and the resultant force is F 3 = 59 lb. Find the measure of the angle between the two forces. => 173.37 or 83.37 or 263.37 or 96.63..

Torque in Two and Three dimension, then the torque acting on the particle with respect to the origi..

Two functions f and g are said to be equal if domain of f = domain of g codomain of f = codomain of g and ..
