Binary value: \_\_\_\_ Working space \_\_\_\_ \_\_\_\_ \_\_\_\_ (b)More people enter the sports stadium and the screen now displays: | 0 | 2 | 5 | 7 | | :--- | :--- | :--- | :--- | Give the binary value that is stored in the register to display the count shown. Binary value: \_\_\_\_ Working space \_\_\_\_ \_\_\_\_ \_\_\_\_ (c) After everyone has entered the stadium, the register stores the binary value: \section*{0000001000000100} Show what the screen will display when this binary value is stored. Display: □ [1] Working space \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ (d) Sensors are used at the entrance to count the number of people entering the stadium. (i) Identify two sensors that could be used to count the number of people entering the stadium.
