question 5 (1 point)
an object travels 10 meters to the right before reversing direction and going 13 meters to the left. jenny reported its displacement as 3 meters, but she was not correct. what did she do wrong?

question 5 options:

she reported the distance instead of the displacement.

she forgot to include the units.

she did not give the direction as either left, or negative.

she did not do anything wrong.

Explanation:

question 1: speed is the total distance covered by an object over a given time regardless of the direction of the distance hence when reporting we report only the value and unit of the speed  which ( km/h )or ( m/s )

question 2: velocity is change in distance covered by an object ( on a straight line) also known as displacement. over a given time by the object hence the direction of the object is considered  

question 3: to calculate for distance traveled by an object you have to sum up the total distance traveled  by the object on a straight line i.e ( 10 + 7 ) = 17 meters

question 4: displacement is change in distance traveled by an object on a straight line in opposite direction i.e ( 7 - 5 ) = 2 meters

question 5: displacement is change in distance traveled on a straight line in opposite direction hence her answer was correct i.e ( 13 - 10) = 3 meters

question 6: speed = distance/time  equation 1

          distance = 5 + 2 = 7 miles

          time = 1/4 hour = 0.25 hour

           equation 1 becomes

           speed = 7/0.25 = 28 mph

question 7: Average velocity = displacement/time equation 1

                   displacement =  5 - 2 = 3 miles

                    time = 1/4 = 0.25 hour

                     equation 1 becomes

                    average velocity =  3/0.25 = 12 mph

question 8: Average speed = total distance / total time   equation 1

            total distance = 0.75 + 0.75 + 0.75 = 2.25 meters

      this is considered the total distance because for each trial she covered                          ramp which was 0.75 meters

            total time = 2.5 + 2.75 + 2.98 = 8.23 seconds

            equation 1 becomes

           average speed = 2.25 / 8.23 = 0.27 m/s

question 9:  It is true because precise is a data that is repeated over and over which might not actually be the actual/correct value while accurate is the data that is closest to the known value

question 10: from the definition in question 9 above the answer is false

1) the andrew carniage's purchase and renovation of skibo castle have been very good and auspicious for the local people of dornoch firth, scotland because this is a turistic attraction for many people who would want to know the castle, the local people would take advantage about this.

2) yes, it could.
