I'm working on a really important physics assignment and i am in deperate need of help! I need to find some scientific problems with reference to the first petrol engine and the some of the first cars ever made (1887-1912). I have to present some problems which i am to solve later on. The problems need to be formulated so that they can be solved by either the inductive or the deductive way. Please guys i'm begging you! Please help me!
