Helium is lighter than air from the lungs.

Explanation:

A balloon filled with the air from lungs will sink to the ground but a balloon filled with Helium floats because helium is lighter than air.

Air is a mixture of many gases.

The air from the lungs is predominantly made up of carbon dioxide and water vapor.

  • Gram per mole of carbon dioxide is 44. Water vapor is 18.
  • Compared to helium which is 4, we see that the gas is lighter.
  • Since the gas is lighter, it will float in air.
  • The main component of air around us is nitrogen gas with a gram per mole of 28.
  • A balloon filled with more of air from the lungs weigh more than that will filled air around and even far more than helium gas.
  • This will cause a helium filled balloon to float.

Answer:

\boxed{p =  {7.4 \times 10}^{2} W} \to \: option \: c.

Explanation:

his \: power \: is \to \\ p =  \frac{mgh}{t}  \\ p =  \frac{1.0 { \times 10}^{2}  \times 1.5 \times 9.8}{2.0}   \\  p= 735 \\  \boxed{p =  {7.4 \times 10}^{2} }

In a semiclassical model of the hydrogen atom, the electron orbits the proton at a distance of 0.053 nm. Part A What is the elec
Bezzdna [24]

Answer with Explanation:

We are given that

r=0.053 nm=0.053\times 10^{-9} m

1 nm=10^{-9} m

Charge on proton,q=1.6\times 10^{-19} C

a.We have to find the electric  potential of the proton at the position of the electron.

We know that the electric potential

V=\frac{kq}{r}

Where k=9\times 10^9

V=\frac{9\times 10^9\times 1.6\times 10^{-19}}{0.053\times 10^{-9}}

V=27.17 V

B.Potential energy of electron,U=\frac{kq_e q_p}{r}

Where

q_e=-1.6\times 10^{-19} c=Charge on electron

q_p=q=1.6\times 10^{-19} C=Charge on proton

Using the formula

U=\frac{9\times 10^9\times (-1.6\times 10^{-19}\times 1.6\times 10^{-19}}{0.053\times 10^{-9}}

U=-4.35\times 10^{-18} J
