Answer:
Evan drive at speed = 81.67 m/hr
Explanation:
Normal speed of Evan = 70 m/hr
Time taken by Evan to visit his grandmother = 35 min =
hr
Distance covered by Evan =
= ![70\times\frac{35}{60}](https://tex.z-dn.net/?f=70%5Ctimes%5Cfrac%7B35%7D%7B60%7D)
=
miles
According to the problem, one day Evan was running 5 minutes late. So, the time Evan has to visit his grandmother is 30 mins.
To reach on time, Evan should be drive at the speed :
Speed = ![\frac{Distance}{Time}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%7D%7BTime%7D)
= ![\frac{\frac{245}{6} }{\frac{30}{60} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B245%7D%7B6%7D%20%7D%7B%5Cfrac%7B30%7D%7B60%7D%20%7D)
= 81.67 m/hr
According to a Physics student in a row boat floating on the same river, the canoe has NO kinetc energy. Zero.
According to another Physics student standing on the riverbank watching both boats, the kinetic energy of the canoe is 12 Joules.
Both students are correct.
Answer:
Mountains can have a significant effect on rainfall. When air reaches the mountains, it is forced to rise over this barrier. As the air moves up the windward side of a mountain, it cools, and the volume decreases. As a result, humidity increases and orographic clouds and precipitation can develop.
Explanation:
