(c) When the temperature reaches \( -18^{\circ} \mathrm{C} \), the pressure of the gas in the cylinder is still equal to that of the atmosphere. Explain, in terms of the particles of the gas, how the pressure remains equal to its original value. Explain, in terms of the particles of the metal, why the decrease in the volume of the metal is less than that of the gas. decrease in the volume of the metal is much less than the decrease in the volume of the gas.

A \( 20-\mathrm{m} \) long steel wire (cross-section \( 1 \mathrm{~cm}^{2} \), Young's modulus \( 2 \times 10^{11} \mathrm{~N} / \mathrm{m}^{2} \) ), is subjecte to a load of \( 25,000 \mathrm{~N} \).

(c) Vektor kedudukan sebuah dron \( A, t \) saat selepas meninggalkan tempat berlepas ialah \( t\binom{30}{15} \) manakala vektor kedudukan dron \( B \) ialah \( \binom{50}{5}+t\binom{10}{10} \). Tentukan halaju bagi dron \( A \) dan dron \( B \). Adakah dron \( A \) dan dron \( B \) akan bertembung? The position vector of a drone \( A, t \) seconds after leaving the takeoff point is \( t\binom{30}{15} \) while the position vector of drone \( B \) is \( \left(\frac{50}{5}\right)+t\binom{10}{10} \). Determine the velocity of drone \( A \) and drone \( B \). Will drone \( A \) and drone \( B \) collide?
