Answer:
athe answer to this question is Synex BA-315
Because fossil fuels are non-renewable resources.
This means, if we run out, we will not be able to reproduce it.
It would be the last that exists. (For oil, it'd be for the next few hundred years.)
A revolution equals 2*pi radians.
As the wheel rotates half every 4 seconds, then it means that it rotates half revolution.
Thus, the angular velocity of the wheel is given by:
w = (pi) / (4) = 0.79 rad / sec
answer
The wheel's angular velocity is 0.79 rad / sec
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.
