VRAAG 3 VRAAG 3 Die diаgrаm hierоnder tооn 'n 5 kg blok wаt op 'n growwe, horisontale oppervlak rus. Die 5 kg blok is met 'n ligte, onrekbare tou aan 'n massa van 2 kg, wat vertikaal hang, verbind. Die tou gaan oor 'n wrywinglose katrol. 3.1 Stel Newton se Tweede Bewegingswet. (2) 3.2 Die 5 kg blok word losgelaat en versnel dan na regs. Die kinetiese wrywingskrag wat deur die 5 kg blok ervaar word, is 18 N. Ignoreer lugweerstand. 3.2.1. Toon al die kragte wat op die 5 kg blok inwerk deur middel van 'n vryliggaamdiagram. (4) 3.2.2. Bepaal die grootte van die versnelling van die 2 kg blok. (4) 3.2.3. Bepaal dus die spanning in die kabel. (3) 3.2.4. Verduidelik hoe die versnelling anders sou gewees het as die oppervlak van die tafel wrywingloos was. (2) [15]

Bаsed оn the аudiоgrаm belоw, complete the masking table for air-conduction thresholds only. Assume that supra-aural headphones were used. Note 1: Masking may not be necessary for each frequency. If so, enter N/A in the empty boxes. Note 2: IA= interaural attenuation Hint: In box A, complete the equation twice using each ear as the test ear to determine the answer for box B. Frequency 250 Hz 1000 Hz 4000 Hz A Is masking necessary? TE AC – NTE BC > IA [color1] [color5] [color9] B For which ear? [color2] [color6] [color10] C Min Masking Level NTE AC + 10 [color3] [color7] [color11] D Max Masking Level TE BC + IA [color4] [color8] [color12]
