in magnets the polarities are exact opposites and in nonmagnetic object the are not so they don't have a magnetic attraction
let the moles of chlorine-35 is n1 and chlorine-37 is n2
now we will use the formula of average atomic mass
here let say
so here since ratio of moles of chlorine 35 and chlorine 37 is more than 1 so chlorine 35 is more in the proportion in this mixture so <em>there is most chlorine atom consist of 18 neutrons</em>
Answer:
When the bowling ball is rolled with a force, this accelerates the ball. That acceleration, when combined with the mass of the ball, produces a force that knocks down the pins.
