Answer: Bohr's model

Explanation:

The Bohr's model is also known as the solar system model which describe that an atoms are basically imagine in the form of solar system. The Bohr's model basically describe about the atoms that it consist of nucleus with the number of electron in an orbit by using the electrostatic attraction.

The Bohr's model are introduced for overcoming the drawback in the Rutherford model as he proposed an idea that at different energy levels the electron can revolve in certain orbits around nucleus.

an observer A fires a gun and another observer B at a distance 1650 m away from A hears its sound . If the speed of sound is 330

Arisa [49]

Answer:

5 seconds

Explanation:

Data provided in the question as per the question is as follows

Distance = 1,650 meter

Speed of the sound is 330 m/s

Based on the given information, the time taken is

As we know that

$Speed = \frac{Total\ distance}{Total\ time}$

So,

$Time\ taken = \frac{Total\ distance}{Speed}$

$= \frac{1,650}{330}$

= 5 seconds

We simply divided the total distance from the speed so that the time taken could be come and the same is to be considered

An ideal monatomic gas initially has a temperature of T and a pressure of p. It is to expand from volume V1 to volume V2. If the

yawa3891 [41]

Answer:

Isothermal : P2 = ( P1V1 / V2 ) , work-done $pdv = nRT * In( \frac{V2}{v1} )$

Adiabatic : : P2 = $\frac{P1V1^{\frac{5}{3} } }{V2^{\frac{5}{3} } }$ , work-done =

W = $(3/2)nR(T1V1^(2/3)/(V2^(2/3)) - T1)$

Explanation:

initial temperature : T

Pressure : P

initial volume : V1

Final volume : V2

A) If expansion was isothermal calculate final pressure and work-done

we use the gas laws

= PIVI = P2V2

Hence : P2 = ( P1V1 / V2 )

work-done :

$pdv = nRT * In( \frac{V2}{v1} )$

B) If the expansion was Adiabatic show the Final pressure and work-done

final pressure

$P1V1^y = P2V2^y$

where y = 5/3

hence : P2 = $\frac{P1V1^{\frac{5}{3} } }{V2^{\frac{5}{3} } }$

Work-done

W = $(3/2)nR(T1V1^(2/3)/(V2^(2/3)) - T1)$

Where $T2 = T1V1^(2/3)/V2^(2/3)$

The air inside the building is easily pressed out the windows because the air is composed of widely spaced molecules in the ____

Ymorist [56]

Hello!

<span>The air inside the building is easily pressed out the windows because the air is composed of widely spaced molecules in the gas phase.

The word "gas" was created by the Netherlandish scientist Jean Baptista van Helmont from the Latin word "chaos". The gas phase consists of molecules with high kinetic energy, that adopt the shape of the container and tend to expand. The molecules are essentially free, and the gravitational pull on them is negligible.

Have a nice day!</span>
