Physics It is easy to burst a gas-filled balloon with a needle than with a nail. It is because Nail exerts more pressure than needle on the balloon. Gas is reactive with the needle. Nail is more longer than needle. Needle exerts more pressure than nail on the balloon. Nail exerts more pressure than needle on the balloon. Gas is reactive with the needle. Nail is more longer than needle. Needle exerts more pressure than nail on the balloon. ANSWER DOWNLOAD EXAMIANS APP
