Compared to yesterday, you did three times the work in the same time. To do so, your power output must have been yesterday's output.

Nine times.

Explanation:

You got three times as much work done (that multiplies it by 3) and you did it 3 times as fast (in one third of the time), that multiplies it by 3 again.

Equation: 3X3 = 9.

I hope this helps you!

Have a great day! :)

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
