Answer:
time = 224 days
Explanation:
given data
thick = 30 m
piezometers = 280 m
head between two = 1.4 m
aquifer hydraulic conductivity = 50 m
porosity = 20%
solution
we get here average pole velocity that is get by using Darcy law that is
Va = 
................1
here Va is average pole velocity and k is hydraulic conductivity and 
is porosity
here v is = 
...........2
v = 50 × 
v = 0.25 m/day
and here average linear velocity Va will be
Va = 
Va = 
Va = 1.25 m/day
travel time for water will be
time = 
time = 224 days
Answer:
second way
Explanation:
robotic kits are simple and easy to make
Answer:
True
Explanation:
When trying to solve a frame problem in Engineering or Physics, it will typically be necessary to draw more than one body diagram.
When we have several parts of the frame or a set of frames, we have the anchor point, as well as the intersections of frames. Besides that, usually, there is a particle or rigid body together with the frame system. In this sense, usually, it is required to analyze a body diagram for the particle or rigid body suspended, as well as the intersections of the frames. So, usually, it will be required a minimum of two body diagrams.
If the system is more complex, or there are many intersections points, it will be required more than two body diagrams.
Finally, indeed, it will typically be necessary to draw many-body diagrams.
