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. Nail is more longer than needle. Needle exerts more pressure than nail on the balloon. Gas is reactive with the needle. Nail exerts more pressure than needle on the balloon. Nail is more longer than needle. Needle exerts more pressure than nail on the balloon. Gas is reactive with the needle. ANSWER DOWNLOAD EXAMIANS APP
