Describe the working of an open end manometer.

Describe the working of an AC generator with the help of a labelled circuit diagram. What changes must be made in the arrangement to convert it to a DC generator?

The difference in the heights of mercury levels in an open end manometer connected to a gas chamber is found to be 175 mm. If the height of mercury level in the smaller limb is more as compared to that in the longer limb and the atmospheric pressure is 755 mm, what is the pressure of the gas ?

Describe the principle, construction and working of an AC generator.

The figure shown a pipe of uniform cross-section inclined in a vertical plane. A U-tube manometer is connected between the point A and B. If the liquid of density rho_(0) flows with velocity v_(0) in the pipe. Then the reading h of the manometer is

A gas is filled into a bulb connected to an open limb manometer. The level of mercury in the open arm is 2.1 cm lower than that in the other arm of the manometer. The atmospheric pressure is 740 mm. What is the pressure of the gas?

A manometer connected to a closed tap reads 4.5 xx 10^(5) pascal. When the tap is opened the reading of the manometer falls is 4 xx 10^(5) pascal. Then the velocity of flow of water is

Describe principle and working of the periscope.

The difference in the heights of mercury columns in a closed end manometer connected to a gas container is found to be 15 cm. What is the pressure of the gas in terms of Pa ?

A glass bulb is connected to an open-limb manometer. The level of mercury on both limbs was same. The bulb was heated to 57^@C . If the room temperature and atmospheric pressure are 27^@C and 750 mmHg, the difference of levels in the two limbs now will be

If we study the vibration of a pipe open at both ends, then the following statements is not true
