un resorte de una maquina industrial se estira un metro al ejercer sobre el 10n de fuerza. se puede afirmar que la contante de elasticidad es de: a) 10m/n. b) 100m/n. C) 10n/m. d) 100n/m. E) 1n/m

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

magnified images possible images can be real = projected onto a screen

small = small current large mag large current

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
