An ideal monatomic gas at 300 k expands adiabatically and reversibly to twice its volume. what is its final temperature?

In an adiabatic process, the following relationship holds:
TV^{\gamma -1} = cost.
where T is the gas temperature, V is the volume and \gamma is the adiabatic index, which is equal to \gamma = \frac{5}{3} for a monoatomic gas.

We can re-write the equation as
T_1 V_1^{\gamma -1} = T_2 V_2^{\gamma -1}
where the labels 1,2 refer to the initial and final conditions of the gas.
Let's rewrite it for T_2, the final temperature:
T_2 = T_1 ( \frac{V_1}{V_2} )^{\gamma-1}

We can now substitute the initial temperature, T1=300 K, and V_2 = 2V_1, because the final volume is twice the initial one. So we find the value of the final temperature:
T_2 = 300 K( \frac{1}{2})^{ \frac{2}{3} } =189 K

just olya [345]
The answer is false. The speed of the astronaut cancels out the force of gravity, causing a 'stationary freefall'. While under these effects, it is not required for an astronaut to 'strengthen' his body.

A 6.00-mH solenoid is connected in series with a 5.0-μF capacitor and an AC source. The solenoid has internal resistance 3.0 Ω w
son4ous [18]

Answer:

5773.50269 Hz

23 A

Explanation:

L = Inductance = 6 mH

C = Capacitance = 5 μF

R = Resistance = 3 Ω

\epsilon = Maximum emf = 69 V

Resonant angular frequency is given by

\omega=\dfrac{1}{\sqrt{LC}}\\\Rightarrow \omega=\dfrac{1}{\sqrt{6\times 10^{-3}\times 5\times 10^{-6}}}\\\Rightarrow \omega=5773.50269\ Hz

The resonant angular frequency is 5773.50269 Hz

Current is given by

I=\dfrac{\epsilon}{R}\\\Rightarrow I=\dfrac{69}{3}\\\Rightarrow I=23\ A

The current amplitude at the resonant angular frequency is 23 A

When a golf ball is hit, it travels at 41 meters per second. The mass of a golf ball is 0.045kg. Calculate the kinetic energy of
Fittoniya [83]

Answer:

  75.645 J

Explanation:

The kinetic energy is related to the mass and velocity by the formula ...

  KE = 1/2mv²

For the given mass of 0.045 kg, and velocity of 41 m/s, the kinetic energy is ...

  KE = 1/2(0.045 kg)(41 m/s)² = 75.645 J

__

The unit of energy, joule, is a derived unit equal to 1 kg·m²/s².
