Ireally need some with this 20 points and brainliest to the person who me. 22) mary started at point a. she walked to point o and then stopped at point b. what is mary’s total displacement from her starting point? what is the total distance that she walked from her starting point? if she walked 700 meters in 5 minutes, what was her speed? (s=d/t)

1. Mary is 500 Meters away  from her starting point because the hypotenuse represents the displacement of Mary from A to O.

2. Since Mary took the long way, she walked a total of 700 Meters. (Because she went from A to O to B, and the sum of 300 and 400 is 700).

3.  Mary walked 140 Meters per minute, because S=D/T. so speed = 700 divided by 5, 140.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
