Science Homework Help

I can not post the actual problems until we start the assignment. I will be able to send you the problems once the assignment is started. Once we start, we must complete the assignment in 1 hour and 40 minutes. For now, I will post some practice problems so that the tutor can make sure they are familiar with the material. I will need all work to be shown and for the tutor to be very punctual and on time. The assignment must be started anytime in the next 20 hours. The assignment will consist of problems the are similar to the practice problems. They will be very straightforward, and almost identical to the problems I will post now. Thank you very much. I have uploaded 4 separate sample assignments. There will be only 20 problems, but they will be taken from all 4 of these assignments so the tutor must have knowledge on all 4 examples.
