VI. The outside mirror on the passenger side of a car is convex and has a focal length of -7.0 m. Relative to this mirror, a truck traveling in the rear has an object distance of 11 m. Find (a) the image distance of the truck and (b) the magnification of the mirror. VII. Light shines through a single slit whose width is 5.6 x 10-4 m. A diffraction pattern is formed on a flat screen located 4.0 m away. The distance between the middle of the central bright fringe and the first dark fringe is 3.5 mm. What is the wavelength of the light? VII. In a Compton scattering experiment, the incident X-rays have a wavelength of 0.2685 nm and the scattered X-rays have a wavelength of 0.2703 nm.

(b) Gee EEN rede waarom die "Vhi Women's Mini Marathon" as 'n mini-marathon beskou word. (3) (2) 5.1.5 Kies die antwoord en skryf slegs die letter (A–C) langs die vraagnommer neer (5.1.5). Die waarskynlikheid dat 'n hardloper die spoorlyn tydens die minimarathon sal oorsteek, is ... A Beslis. B 0%. C 100%. (2) 5.2 Die sitplekplan vir 'n bioskoop tydens die Covid-19-pandemie word hieronder getoon. Sitplekke gemerk met 'n 'X' moet oopgelaat word om aan sosiale distansiëringsregulasies te voldoen. Gebruik bogenoemde sitplek plan en die inligting om die vrae wat volg te beantwoord: 5.2.1 Aan watter kant van die bioskoop is sitplek E4 vanaf sitplek E15 wanneer iemand na die skerm (screen) kyk? (2) 5.2.2 Aanvaar dat toestande voor Covid-19 geld en dat al die sitplekke beset word. (a) Noem die ry- en sitpleknommer van die middelste sitplek in die 8ste ry vanaf die skerm (screen).
