4 Enter the position of the solar cell on the base mat where the conveyor turns at its slowest speed, in the 'furthest from lamp' bo of table 3.2. Choose the input and output energy used in your transducers. Fill in the transducer diagrams in table 3.1. Input energy Type of transducer Output energy solar cell motor Table 3.1 In table 3.2, record the amount of turns the conveyor belt made in 30 seconds, and then calculate the Revolutions per Minute (RPM). Solar Cell Position Closest to lamp: 15" mark Turns in 30 secs Revolutions per Minute (RPM) Halfway mark Furthest from lamp:... mark Table 3.2 Compare the results in table 3.2. Write a brief eplanation of your findings. SW1.3
