We're on the very first chapter of the textbook, going over dimensional analysis and conversions, and I'm already in trouble over the homework. Could you give me a hand with these problems?
"Suppose your hair grows at the rate of 1/32 inch per day. Find the rate at which it grows in nanometers per second."
Now, I'm capable of converting inches into nanometers, and days into seconds, and then putting one on top of the other, but I don't think that's the way my teacher wants it done.
"The speed of light if about 3.00 x 10^8 m/s. Convert this figure to miles per hour."Same problem. I know how to get meters into miles and seconds into hours, but I don't know how to do it the "right" way.
Thanks, guys. I'd really appreciate some help.
