(e) The steel cable from the crane has a circular cross-section of diameter \( 1.5 \times 10^{-2} \mathrm{~m} \) The cable is 12 m long.

Calculate the extension of the cable caused by the weight of the beam. You can assume that the weights of all cables are negligible.

(a) Figure 1 shows an incident ray of light being partially reflected at the boundary between glass \( \mathbf{A} \) and glass \( \mathbf{B} \). The refractive index \( n_{\mathbf{A}} \) of glass \( \mathbf{A} \) is 1.461

The speed of light in glass B is \( 3.252 \% \) less than the speed of light in glass \( \mathbf{A} \).
