CFI and I departed ZZZ for survey work near ZZZ1 airport. This imagery project required us to be below 117 kts ground speed at 1;000 feet AGL. CFI was instructing me on how to fly survey lines following their FMS system. Because the aircraft was so slow; the gear warning horn was activated. CFI pulled the circuit breaker. After completion of this project; we headed for other projects to the east. We were cleared into Class Bravo airspace and started our pre-coordinated survey work. CFI handled all radio calls at this point as he instructed me on flying the lines. After completing this project; we started another which ran north and south; and was located east of ZZZ2 and ZZZ3. About half way through our project; we were instructed to make a left turn to the north by ATC. CFI asked if instead we could head to another project northwest of ZZZ4 since clouds were interfering with our current project. This was approved by ATC. After completion of this project; we landed at ZZZ4 for fuel and to reevaluate the weather. After we departed ZZZ4 we headed to one more project. This project was flown at 1;000 feet AGL and had a speed restriction to be below 120 kts groundspeed. CFI pulled the circuit breaker and I did not hear a gear warning horn. I did not recognize that he had pulled the breaker at the time. Upon completion of this project; we headed back to ZZZ. I was being instructed on power management. I did not descend fast enough for the straight in approach to Runway XX we were assigned by Tower. On about a 1.5 mile final; we were hundreds of feet too high and our speed was 180 kts. I said 'I need to level off' because I wanted to slow to 160 to put down the gear. CFI said 'No you need to get down now' and pushed the yoke forward into a steep descent which I then continued. CFI began adjusting power; activating speed brakes; putting flaps down and the gear handle. He was also telling me to get on center line. Seconds before touchdown; there was a call on the radio 'Go around; go around; go around'; however; I knew it was not CFI saying it and neither of us knew who was saying it or that it was directed at us since we were focused on landing. The airplane touched down around on center line and slid a few hundred feet drifting to the left side of the runway. CFI and myself had both failed to identify that the gear was down and locked. The gear warning horn and gear circuit breaker had been pulled by CFI without my knowledge. We exited the plane without any injuries. The Fire Department came and investigated to find that no one was injured and there was no risk of fire. This was only my second day of flying with [Company] as part of a three week training program. Prior to my employment [Company]; I had no prior experience with aircraft [type]. I feel that there are many things that contributed to this but it could have been avoided. Below I have listed things that contributed or would have helped avoid this occurrence. - Had the circuit breakers not been pulled; I think we would have had a much better chance of identifying the gear was not down. - If there were established procedures for when a circuit is pulled for a project; that both pilots are required to verify it has been pushed back in before landing. - If more time was given to review the POH; checklist and flows for the aircraft. - If either CFI or I were completely in control of the aircraft rather that splitting responsibility. - Double checking to make sure there were three green lights indicating the gear was down and the front wheel was seen in the mirror.
