Answer:
Explanation:
moment of inertia of man
= mr² , m is mass of man and r is radius of table .
= 53 x 2.9²
=445.73
angular momentum of runner = mvr , v is velocity of runner .
53 x 3.6 x 2.9 = 553.32
angular momentum of turntable
= Iω , I is moment of inertia and ω is angular velocity of table .
= 76 x .2 = 15.2
Total angular momentum = 553.32 - 15.2
= 538.12
Let the common velocity when the runner comes to rest with respect to turntable be ω.
total moment of inertia of the system
= 445.73 + 76
= 521.73
Applying law of conservation of angular momentum
total initial angular momentum = final angular momentum
538.12 = 521.73 ω
ω = 1.03 rad /s .
Answer:
The formula for Impedance for circuit with R, C, and L are:
The impedance Z of the series RLC circuit depend upon angular frequency ω. Impedance is measured in ohms and resistance (R), inductance reactance and capacitive reactance. Series RLC circuit consist of the resistance, a capacitance and an inductance connected in the circuits. Electrical impedance is the measurement of the opposition that a circuit present in a current.
Answer:
Manometer is a measures to the atmospheric measure.
Barometer is a measure to the atmospheric pressure.
Explanation:
- Manometer is there are two types (1) closed tube (2) open tube, is filled with liquid water and mercury and the tube.
- Manometer do not need equal size of the tubes to the open ended manometers.
- Manometers is simple to attach on this filled to the high pressure gas in the bulb,this gas pressure put on the tube.
- Manometer is the attach the gas and vacuum gas to the open of the air, its high pressure gas is to the one of end.
- Manometer are filled the mercury to the heavy liquid manometer filled the liquid water and oil with the mercury.
- Barometer is to the close ended tube and the glass tube is the open and that a vacuum is the other end.
- Barometer can the u shaped and the closed ended tubes to the barometers.
- Barometer is the mercury closed end and vacuum is the tallest point in the liquid.
- Barometer is also used to be a table or left standing and also be digital and portable traditional glass, may find the digital clock .
- Barometer are filled the mercury to the high level liquid must be extreme tall in change in atmospheric pressure.
