Mr. Franklin uses a machine that has an efficiency of 80%. The machine applies a force of 800N through a distance of 20 m. Mr. Franklin applies a force of 50N on the machine. Through what distance does Mr. Franklin apply the force?

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

not moving. pos accel,
