Two friends each drive a car down highway 101 during the same 10s interval jodis car moves at a constant 60 mph and julie car transitions from a speed of 20mph to a speed of 30mph answer whose car has greater acceleration

acceleration is the rate at which   velocity changes. jodi's car stayed at 60mph while julie's car went from 20mph to 30mph. so julie had an acceleration of 10mph and jodis did not change.

explanation: honestly i'm not 100% sure but maybe i

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

snell's law

refractve index = sin incidence / sin refraction
