Max is taking his human, Frank, for a walk. Answer the three questions below using three significant figures. Part A: You can see that Frank is getting dragged behind Max, and this means that Max has to pull with a force of 290 N. How much power ( P 1 ) does Max have to supply in order to pull Frank at a speed of 0.425 m/s?

123.25 W

Explanation:

Part A

Power: The can be defined as the rate at which energy is used up. The S.I unit of power is Watt(W).

From the question,

P1 = F×v Equation 1

Where P1 = Max's power, F = Force used by max to pull Frank, v = velocity of Frank.

Given: F = 290 N, v = 0.425 m/s

Substitute into equation 1

P1 = 290×0.425

P1 = 123.25 W.

Hence the power supplied by Max = 123.25 W

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
