I appear in the morning but am always there.
You can never see me though I am everywhere.
By night I am gone, though I sometimes never was.
Nothing can defeat me but I am easily gone.
Light. Without light you wouldn’t be able to see anything. And light is made up of all the colors of the rainbow. Adding light to a word can mean it weighs less and light has no mass.
Joe and Andrea want to copy three 60-minute cassette tapes. They have a 2-cassette recorder to copy the tapes, allowing them to copy two tapes at a time. Each side takes 30 minutes to be copied, so two tapes can be copied in an hour and the third will take another hour. Andrea bets Joe she can copy all three tapes in 90 minutes. Does she win the bet?
In the first 30 minutes Andrea copies the A sides of tape 1 and 2.
In the second 30 minutes, she copies tape 1 side B and tape 3 side A (finishing Tape 1).
In the last 30 minutes, she copies tape 2 side B and tape 3 side B.
