Which of the following is an illuminated object? a lightbulb a fire the Sun the Moon

Harlamova29_29 [7]

The lightbulb, the fire, and the Sun all create light from some energy source.

The Moon doesn't create light. The parts of it that the Sun shines on
are visible, the parts of it that the Sun doesn't shine on are not visible.

Just like a rock on the ground at night, the Moon must be illuminated
by a flashlight in order to be seen. The Sun is the flashlight.

A gas undergoes two processes. In the first, the volume remains constant at 0.170 m3 and the pressure increases from 1.50×105 Pa

Mnenie [13.5K]

Answer:

$W_{T} = - 24 kJ$

Explanation:

The work (W) done by the gas can be calculated using the following equation:

$W = p*\Delta V = p*(V_{f} - V_{i})$

<u>Where:</u>

p: is the pressure

[tex}V_{f}[/tex]: is the final volume

[tex}V_{i}[/tex]: is the initial volume

In the first process, the work done by the gas is:

$W_{1} = p*\Delta V = p*0 = 0$

Since the volume remains constant, the total work done by the gas is equal to zero.

In the second process, the work done by the gas is:

$W_{2} = p*(V_{f} - V_{i}) = 6.00 \cdot 10^{5} Pa*(0.130 m^{3} - 0.170 m^{3}) = -24 kJ$

Now, the total work done by the gas during both processes is:

$W_{T} = W_{1} + W_{2} = 0 + (-24 kJ) = - 24 kJ$

Therefore, the total work done by the gas during both processes is - 24 kJ.

I hope it helps you!
