The hall voltage will be calculated using the formula:
E = Blv
where:
>Hall voltage: E = ?
>Magnetic field:
B = 0.200 Tesla or Wb/m^2
>Width of conductor or Diameter of Aorta:
l = 2.60 cm, converting to meter = .0260 m
>Velocity of charge flowing:
v = 60 cm/s, converting to meter = 0.6 m/s
Substituting the given :
E = (0.200 Wb/m^2) * (0.260 m) * (0.6 m/s)
E = (0.200 Wb/m^2) * (0.156 m^2/s)
E = 0.0312 Wb/s
Since 1 volt = 1 Wb/s then,
E = 0.0312 V or 31.2 mV
P = m*v
conservation of momentum suggests
initial momentum equals final momentum
mv-initial = mv-final
(0.0010 kg)(50 m/s) = (0.0010 kg + 0.35 kg)v
thus:
v = (0.0010)(50)/(0.351) = 0.142 m/s
The rotation of the Earth causes this movement. We watch stars rising in the East, passing overhead, and setting in the West as the Earth spins eastward at over one thousand miles per hour. The Sun, Moon, and planets appear to travel through the sky in the same way as the stars do.
Answer:
alchol and water homogeneous
When two circuit elements (e.g., light bulbs, resistors, etc.) are in PARALLEL, the voltage drop across each element must be the same.
(choice-b)
When the same two circuit elements are in SERIES, the current through each element must be the same.
