Want this question answered?
No, it is not a simple machine itself, but a complex machine made up of multiple simple machines. The fan would be a screw, and the rudder would be a lever.
Most good playgrounds are located on the sites of local schools. They have safe and fun playground equipment.
Yes
That isn't possible, not with a simple machine and not with a complicated machine, since otherwise, conservation of energy would be violated.
no
a wedge
Ok I think that the answer would either be simple machine or compound machine but I'd double check first..
No. Gears are a type of simple machine. Combined with another simple machine, it would then make a compound machine.
A screw is the simple machine which holds two boards together. In this case it is not acting as a machine though.
It would be a kids' playground. There will be more than one kid on the playground, so there are kids. Then to make that plural, you would have to ad only an apostrophe and not apostrophe then an "s". Where as if there were only one kid on the playground then it would be a kid's playground, because there would only be one object there. Hope this helped.
a complex machine would be a car, but a simple machine would be a wheel and axle. an example of a wheel and axle would be a steering wheel
It's a tool
