78% - not bad for an English major. My engineer husband did help with a couple of questions though.
I think I could have gotten a couple more right if I took time to figure them, like F(net)=ma, but I was too lazy. And some I didn’t actually “know” but reasoned out, like the question on horsepower. I know scientists have egos, but they’d never name a unit of power after themselves. (”Watt” was obviously wrong by my thinking). And the question on catalytic converters threw me. I thought palladium at first, but since it is a valuable metal, and I haven’t heard much in the way of CC thefts, I reasoned it had to be something else. Wrong! (But don’t tell the thieves out there!)
