Answer:
Average Velocity= 1.16m/s
Explanation:
Distance initially run= d1= 925m
distance finally run= d2= 673m
Time= t1= 10m
time= t2= 13m
Average Velocity= Total distance covered/ total time
=d1+d2/t1+t2
= 925+673/ 10(60) + 13(60) {converting mins to secs)
= 1598/1380= 1.157≅ 1.16m/s
Around 750 to 1,500.
Hope I helped!
B is a trough.
A trough is the opposite of a crest, in that it occurs at the maximum negative displacement of a wave.
In this problem, A would be the crest, C would be the wavelength, and D would be the amplitude.
