Songs that were country: 3/10 (It was before 15/50, till I divided the numerator and denominator by 5 to get my answer, and the simplest answer is 3/10.)
Rock songs: 2/5 (It was before 20/50, till I divided the numerator and denominator by 10 to get my answer.)
World songs: 1/5 (It was before 10/50, till I divided the numerator and denominator by 10 to get my answer.)
Classical songs: 1/10 (It was before 5/50, till I divided the numerator and denominator by 5 to get my answer.)
Answer:
25
Step-by-step explanation:
He's already out of 50 bucks, because he didn't profit enough for his loan. So now we have -50, then in the next 2 months he records a profit of -75. We add that onto -50, to make -125. Then he makes 150 in profit so that's good good job Billy, -125+150=25. I hope this is right LOL
It is given that at the moment the first pulse reaches the wall, a second pulse is sent down the spring. Now, when the two pulses meet they will be subject to the principle of superposition and as one is upside down (the reflected pulse) and the other is up (the second pulse), there will be a nullifying effect and the spring will appear straight for that split moment. Thus we can say that there will be a destructive interference where one pulse will destroy the other or in other words nullify the other's existence. After that moment the pulses will move towards their respective ends as if nothing happened.
Hence, Option B is the correct option.
