i have one glass cylinder containing water fitted with rubber cork. there are two tubes in rubber cork one long inlet tube which passes into the water 20cm of its length having its other end is open to air has inner diameter 0.7mm. Other short outlet tube it has inner diameter 0.7mm. if i took air in from mouthpiece from mouth(if i breathe through that device) then how much pressure i will feel. i mean how much pressure water will give to air i'll take in? please ans for that. thank u

Which of the following helps to determine whether a body will be in thermal equilibrium with another body? thermal energy zeroth law of thermodynamics numerical scale first law of thermal thermodynamics 2A thermocouple works on the principle of -------------------- variation of e.m.f with temperature variation of volume with temperature variation of pressure with temperature variation of resistance with temperature 3The fundamental interval of a thermometric scale refers to --------------------- triple point of water difference between upper and lower fixed points ratio of the upper to the lower fixed point temperature of steam at standard atmospheric pressure 4The ice and steam points on a thermometer correspond to X and 50mm respectively. A temperature of 60degree celcius corresponds to 52mm on the thermometer. Calculate the value of X 4 mm 8 mm 10 mm 20 mm 5A railway line is laid with 10m length of rail on a day when the temperature is 2:50oC . There is a gap of 0.5cm between the rails. Find the temperatur

a=1,b=1,c=1

A square plate of side 10 cm is made of a metal of linear expansivity 210−5/K. As the plate is heated from 30oC to 100o, the area of one face of the plate will increase to?

A platinium resistance thermometer has resistance of 52.5 ohms and 9.75 ohms at 0 degrees celcius and 100 degrees celcius respectively. When the resistance is 8.25 ohms, find the temperature

How do charges move through an insulated wire connected across a battery? Please use the terms potential difference, current, conductor, and insulator in your answer. And can you try to keep it simple and short? Thank you so much.

Which of the following statements is most correct?
A Calculating beta coefficients using a calculator is not a legitimate method of
estimating beta because it measures changes in an individual security’s return
regressed against time.
B The general equation: Y = a + bX + e, is the standard form of a simple linear
regression where b = beta, and X equals the independent return on an individual
security being compared to Y, the return on the market, which is the dependent
variable.
C The beta coefficient used in the SML equation should reflect the expected volatility
of a given share’s return versus the return on the market during some future period.
D The CAPM is an ex ante model, which means that all of the variables should be
historical values that can reasonably be projected into the future.
E All of the above statements are false.
