Aslingshot obeying hooke’s law is used to launch pebbles vertically into the air. you observe that if you pull a pebble back 20.6 cm against the elastic band, the pebble goes 4.8 m high. assuming that air drag is negligible, how high will the pebble go if you pull it back 41.2 cm instead?
how far must you pull it back so it will reach 9.6 m ?
if you pull a pebble that is twice as heavy back 20.6 cm , how high will it go?

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

magnets not strong enough
