Una es un conjunto de elementos móviles y fijos cuyo funcionamiento posibilita aprovechar, dirigir, regular o transformar o realizar un con un fin
determinado.
Las son ingenios que utilizan los seres humanos para realizar trabajos
con un menor esfuerzo. Desde la antigüedad se considera que son cinco las grandes máquinas simples:
el plano , el , la rueda, la y la polea.
Los son elementos destinados a y/o fuerzas
y/o desde un elemento motriz ( ) a un elemento conducido
( ), con la misión de permitir al ser humano realizar determinados trabajos con mayor
comodidad y menor

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
