What instrument
Probably a microscope.
A physicts
False. Cetology is study of whales, dolphins, and porpoises; cytology is the study of cells.
Gravity? the strength of the floor?
This study would fall under the broad heading of ceramics at least. Optics is a study of light waves and their interactions.
What is the purpose of the following sentence?I think it would be best to study the problem carefully.
Magnifying / Microscope lens

youd go faster, but the slide would get sticky after a while and would give someone a wedgie or pull their pants down!
My guess would probably be designing water slides
You can use a spray bottle to mist water onto a slide to make it slippery or a hose to wet it more evenly.
Crocodile Mile was like the Slip'n'slide. It was a long inflatable slide that you would hook up to a hose which would feed water throughout the surface of the slide. Then you would run and slide across it. They very quickly started springing air leaks though, rendering the toy useless.
Typically you would tee into the plumbing after the pump and filter with a small hose and a valve that runs to the plumbing on the slide.
If a water slide was dry, the lack of water would increase friction between the slide surface and any riders. This increased friction could make it more difficult for riders to move smoothly down the slide, potentially causing discomfort or slowing down their speed.
It deepens if you are dong it for over 10 years you believe it or not 150k per year but if you just start out it would be about 80k per year.

Yes, friction is useful on a slide because it helps to slow you down and prevent you from sliding too quickly or uncontrollably. It also provides enough grip for you to stay on the slide without slipping off.
No, "slide" is the present tense. The future tense would be "will slide".
