TENIENDO EN CUENTA ESTA ECUACIÓN RESPONDE DE LA 1-5: LA ECUACIÓN DE UNA ONDA ES: y=7cos 2π(t/0.33 - x/9), si la distancia se mide en metro y el tiempo en segundo calcula: cuál es la amplitud, periodo, frecuencia, longitud de la onda, velocidad de propagación​

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

Awoman holds a book by placing it between her hands such that she presses at right angles to the front and back covers. the book has a mass of m = 1.8 kg and the coefficient of static friction between her hand and the book is μs = 0.67. no attempt 50% part (a) what is the weight of the book, fgb in newtons?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
