Another name for these two words is "constant" and you want to have a "constant", because you want something to compare your experimental group to, to see whether data had changed or not. So you have placebos or a double- blind to compare your experimental group to it and also so you know you don't have a bias or anything in the study.

erik [133]

Answer:

P = 36068.7 Watt

Explanation:

As we know that average power is the ratio of total work done and total time interval

so we will have

Power = \frac{Total \: Work}{time}

now we know that

Work = \frac{1}{2}mv^2 + mgh

W = \frac{1}{2}(700)(11^2) + 700(9.8)(9.6)

so we will have

W = 42350 J + 68856 J

W = 108206 J

now power is given as

P = \frac{108206}{3}

P = 36068.7 Watt
