Answer:
1.12 m
0.08291 m
Explanation:
u = Upstream velocity = 0.4 m/s
Re = Reynold's number =
(turbulent)
= Viscosity of water = 
Here the flow is turbulent so we have the relation

The approximate location downstream from the leading edge where the boundary layer becomes turbulent is 1.4 m
Boundary layer thickness relation is given by

The boundary layer thickness is 0.08291 m
Answer:
Explanation:
opposite charges attract each other, while rubbing the objects together they developed opposite charges which caused them to drift together
The electromagnetic spectrum is made up of waves of different lengths, forming bands.
