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
<h2>
Answer:It is not affected by the change in media.</h2>
Explanation:
Transverse waves are those waves where the medium particles vibrate perpendicular to the direction of propagation.
Transverse waves do not require any medium.
They travel with same speed in any medium.
Electromagnetic waves are transverse waves where the medium particles vibrate perpendicular to the direction of propagation.
So,their speed is same in any medium.
Answer:
59.503987 seconds
Explanation:
b = Proportionality constant = 50 Ns/m
g = Acceleration due to gravity = 9.81 m/s²
m = Mass of object = 700 kg
We have the equation of velocity
The equation of motion
when x(t)=2000
The time taken is 59.503987 seconds
