I think I chose 2 because you count how many times it goes from positive to negative or negative to positive. But I think might have misread the graph, not sure lmao
For crime, compliance and non-compliance, and law reform hasn't been asked in a while, so I wouldn't be surprised if the question involved those themes.
"In a thought experiment, a jet is travelling at 0.5 c relative to the ground, towards a train
that is travelling at 0.1 c relative to the ground.
What is the speed of the light emitted from the train’s headlight, as measured by a pilot
in the jet?"
So the answer is 1.0c
Can anyone...
