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