A diver named Jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the
kodGreya [7K]

Answer:

3.73994

No,

Explanation:

P_1 = Pressure at the bottom of the lake = 3.5 atm

P_2 = Pressure at the top of the lake = 1 atm

V_b = Volume at the bottom of the lake

V_s = Volume at the top of the lake

T_1 = Temperature at the bottom of the lake = 4 °C

T_2 = Temperature at the top of the lake = 23 °C

From ideal gas law we have the relation

\dfrac{P_1V_b}{T_1}=\frac{P_2V_s}{T_2}\\\Rightarrow \dfrac{V_b}{V_s}=\frac{P_2T_1}{P_1T_2}\\\Rightarrow \dfrac{V_b}{V_s}=\frac{1\times 277.15}{3.5\times 296.15}\\\Rightarrow \dfrac{V_s}{V_b}=0.26738^{-1}\\\Rightarrow \dfrac{V_s}{V_b}=3.73994

The ratio is 3.73994

As Jacques is ascending if he holds his breath his lungs acting like a bubble would expand. Hence, it is not safe to hold his breath while ascending,

Two coils, held in fixed positions, have a mutual inductance of M = 0.0034 H. The current in the first coil is I(t) = I0sin(ωt),
creativ13 [48]

Answer

given,

I(t) = I₀ sin(ωt),  

M = 0.0034 H, I₀ = 5.4 A,  ω = 143 rad/s.

a) magnitude of induced emf in terms of M and I

    ε₂ = -M\dfrac{dI}{dt}

b) magnitude of induced emf in terms of M, Io, and ω

      \dfrac{dI}{dt}=\dfrac{d}{dt}(I_0sin(\omega t))

      \dfrac{dI}{dt}=I_0 \omega cos (\omega t)

now,

      ε₂ = -MI_0 \omega cos (\omega t)

c) maximum value of  |ε2|, εmax, in terms of M, I₀ , and ω.

       |ε₂| = |-MI_0 \omega cos (\omega t)|

      for ε_{max} , cos ωt = 1

       ε_{max} = MI_0 \omega  

d) numerical value of εmax in V.

      ε_{max} = MI_0 \omega  

      ε_{max} = 0.0034\times 5.4\times 143  

      ε_{max}  = 2.63 V

What is the physical properties of radon
ryzh [129]

Answer:

<h2 /><h2>1) Radon is colorless at standard temperature and pressure and it is the most dense gas known. At temperature below it's freezing point is has a brilliant yellow phosphorescence. It is chemically unreactive, it is highly radioactive and has a short half life.</h2>

<h2>2) 7.5 times heavier than air and more than 100 times heavier than hydrogen. The gas liquefies at −61.8 °C (−79.2 °F) and freezes at −71 °C (−96 °F). On further cooling, solid radon glows with a soft yellow light that becomes orange-red at the temperature of liquid air (−195 °C [−319 °F]).</h2>

<h2 /><h2 /><h2 />

Explanation:

<h2>I think this much is enough , as more information </h2><h2>is given in other answer if more is needed just </h2><h2>comment me I will answer you there only.</h2>
