A mercury manometer is connected on one side to a bulb containing argon, while the other end is open to atmospheric pressure, wh
belka [17]

Answer:

740, mm of Hg

Explanation:

The pressure of argon , in mm of Hg = difference in the level of mercury on either side of the manometer.

mercury column  in the open end of the manometer is 22 mm below that in the side connected to the argon and 762 mmHg,  end is open to atmospheric pressure.

therefore, The pressure of argon , in mm of Hg  =762 -22 = 740, mm of Hg

What must be the diameter of a cylindrical 120-m long metal wire if its resistance is to be 6.0 ω? the resistivity of this metal
Free_Kalibri [48]

The resistance of the cylindrical wire is R=\frac{\rho l}{A}.

Here R is the resistance, l is the length of the wire and A is the area of cross section. Since the wire is cylindrical A=\frac{\pi d^2}{4}. Rearranging the above equation,

A=\frac{\rho l}{R}\\  \frac{\pi d^2}{4}=\frac{\rho l}{R}\\  d=\sqrt{\frac{4\rho l}{\pi R}}

Here l=120, R=6, \rho=1.68(10^{-8}).

Substituting numerical values,

d=\sqrt{\frac{4(1.68)(10^{-8}) (120)}{\pi (6)}}\\ d=0.0006541

Te diameter of the wire is 0.6541 mm
