The answer would be Liquids. They can pass through solids though. Hope this helped! :)
Answer:
a)this graph is also a line b) in both cases we have a uniform movement
Explanation:
In this exercise we have a uniform movement
v = d / t
d = v t
in the table we give some values to make the graph
t (s) d (m)
1 10
2 20
3 30
In the attached we can see the graph that is a straight line
we have another vehicle at v = 50 me / S
t (s) d (m)
1 50
2 100
3 150
this graph is also a line
b) in both cases we have a uniform movement
Answer:
The current through the tube is 73.39A.
Explanation:
The relationship between the resistivity , the electric field , and the current density is given by
This equation can be solved for to get:
Since the current is
Now, for the tube of mercury , , and the area is ; therefore,
Hence, the current through the mercury tube is 73.39A.
I'd say the answer to this on is d.Facts as they are using the temperatures in the graph and the temperatures are not just estimates
