The average Power created by the force F is; P_avg = 1440 W
<h3>What is the Average Power?</h3>
We are given;
Initial velocity; u = 0 m/s
Acceleration; a = 0.08 m/s²
Time; t = 1 minute = 60 s
Formula for distance is;
s = ut + ¹/₂at²
s = 0 + (¹/₂ * 0.08 * 60²)
s = 144 m
Work done by force is
W = F * s
W = 600 * 144
W = 86400 J
Average power created by a Force is;
P = workdone/time taken
P = 86400/60
P = 1440 Watts
Complete question is;
A sled is being pulled along a horizontal surface by a horizontal force F of magnitude 600 N. Starting from rest, the sled speeds up with acceleration 0.08 m/s² for 1 minute.
Find the average power Pavg created by the force F.

9 workers
7 workers can make 210 pairs of cup in 6 days, so:
1 worker can make 30 pairs of cup in 6 days, so:
1 worker can make 5 pairs of cup in 1 day.
Using this info, because
the workers need to make 450 pairs of cup in 10 days,
they need to make 45 pairs of cup in 1 day,
each worker can make 5 pairs of cup in 1 day,
so 45/5 = 9 workers
voila!
The appropriate conclusion of the hypothesis is; The researcher has statistical evidence to conclude that the population mean shower length for high school students is greater than 10 minutes.
<h3>What is the conclusion of the hypothesis?</h3>
We are given;
Sample size; n = 125
Population mean; μ = 10 minutes
Sample Mean; x' = 14.7 minutes
Now, we are told that the hypothesis was carried out and the p-value was 0. Now, the significance level is α = 0. 05 and this means that the p-value is less than the significance level.
In conclusion, we will reject the null hypothesis and conclude that there is sufficient evidence to conclude that the population mean shower length for high school students is greater than 10 minutes.

The pH scale is a measure of how acidic a solution is.
<h3>What is a pH scale?</h3>
The unit of measurement to determine how acidic or basic a solution is, is done via a pH scale, which ranged from 0 to 14, on which 0 to 6.9 means that the solution is acidic, and 7 is neutral.
Hence, the pH scale helps to determine the acidic amount of the solution.
