Answer:
The observation that could be made in regards a neon light placed in one evacuated (airless) chambea r, and battery powered radio placed in a second evacuated chamber, switched on at the same time by remote control, is that they are managed as capacitors.
Explanation:
Capacitors, also known as condensers, store energy and, we can also see them in the sky, they are the clouds.
Capacitors are made of two electrical conductors, separated by an insulator, when you add electrical energy to a capacitor you are charging a capacitor, the opposite is known as discharging.

10. True
Answer:
convention cells
Explanation:
In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it expands and becomes less dense and thus more buoyant than the surrounding fluid. The colder, denser part of the fluid descends to settle below the warmer, less-dense fluid, and this causes the warmer fluid to rise. Such movement is called convection, and the moving body of liquid is referred to as a convection cell. This particular type of convection, where a horizontal layer of fluid is heated from below, is known as Rayleigh–Bénard convection. Convection usually requires a gravitational field, but in microgravity experiments, thermal convection has been observed without gravitational effects.
A volcanologist is a geologist who studies the process involved in the formation of a volcano. He also studies the eruptive nature of the volcano along with their current and historic eruptions.
The tasks done by a volcanologist do to study volcanoes are =
1. use autoclaves to imitate the interior of a volcano
2. simulate volcanic explosions with computer programs
3. study lava samples
4. listen to the sounds of the interior of a volcano
<u>The eukaryotic cell differs from the prokaryotic cell in the following ways:</u>
- The eukaryotic cells have a <em>membrane-bound nucleus</em>, whereas the prokaryotic cell has a <em>non-membrane bound nucleoid</em>.
- According to the size, the eukaryotic cell is <em>large</em> when compared to the prokaryotic cell.
- The eukaryotic cell undergoes cell division through a process called <em>mitosis or meiosis</em>, whereas the prokaryotic cell divides through <em>fission or budding.</em>
- Membrane-bound <em>cell organelles</em> are present in eukaryotic cells whereas absent in a prokaryotic cell.
- The process of <em>gene expression</em> occurs in two different cell organelles (nucleus and cytoplasm) in the case of eukaryotic cells, whereas in the prokaryotic cell it occurs in the cytoplasm.
