IF I CAN HAVE AN ANSWER BY THE END OF THE DAY THAT WOULD HELP! I have to get this in by tomorrow morning at 8:30am. April 1 2021
Aleksandr [31]

Answer:

The time of day the second time the student measured the length of the fence shadow was either earlier or later than the first time she measured the shadow.

Explanation:

As the first time the student measured the shadow of the fence gave an answer of 2 meters, the second time gave an answer of 3 meters. For this reason, the shadow is longer in length. This means that the sun is closer to the horizon, yielding a light beam that is closer to the ground.

Moreover, if the sun was directly above the fence post, there would be no shadow. However, because the sun is closer to the horizon, showing that it is earlier or later then the first measurement, the second measurement has a longer shadow.
