Like if you were walking in the same direction as the train would be traveling, so you end up moving faster than the train. is that harder than walking in the opposite direction of train travel.

Im sure most will answer that there is no difference, but that would mean if the train was at light speed it would only take a tiny amount of energy by the traveller to exceed the speed of light.

all hypothetical of course, and let assume the train can get to that speed in the first place.

I see advertisements for kits to grow Morel mushrooms and they say that if you follow their directions you can grow them anywhere in the US. I understand they are especially difficult to grow. Will this work in Connecticut?

A water sample contains 0.0700 grams of arsenic in 10.0L of water. What is the concentration of the arsenic in

parts per million (ppm)?

Ok, we have a physics project we need some good ideas for. It has to be a self propelled car or airplane using no kits or chemical reactions. These are the specifications:
Max Height: 1.0 m
Max Width 1.0 m
Max Length 1.0 m
Max Mass 4.5 kg

No explosives, hazardous or dangerous materials can be used. No chemical storage of energy may be used. No biologically active components (no animal power).

Also, we cannot built a launcher it must be SELF PROPELLED,

If you answer this thank you so much. And please only serious answers, we aren't looking for any funny guys.

In my Biology class everyone has to teach the rest of the class about an aspect of ecology. My aspect is ecosystems and niches. We all also have to have an activity for the class to do to help them learn. Does anyone have an idea for a game or something. By the way, this is tenth grade bio, so it should probaly be something at that level. Thanks.
