5.How do simple machines make work easier?(1 point) a. They decrease the distance needed between a person and an object, allowing the person to apply more force and do more work.

b. They magnify the force being applied, thereby increasing the work they can do with no extra energy exerted by the person using the machine.

c. They reduce the amount of force needed to move an object to do the same amount of work.

d. They increase the distance over which a force is needed, doing more work with less force.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
