<span>One property of an electron is that it has a net charge of -1. This is because the magnitude of the electric charge of an electron offsets the elementary electric charge of a proton.</span>
Because different materials have different molecular organizations.
Wow, this is a good question. I'm going to go with B, it increases. Thanks! You strained my brain! :D
<h3>160 W</h3>
If the temperature is doubled to 2t, the rate at which it will now radiate is 160 W.
<h3>What is meant by emissivity?</h3>
- The ability of a substance to reflect heat radiation from its surface is measured by its emissivity.
- Thermal radiation is a type of electromagnetic radiation that includes infrared radiation, which the human eye cannot perceive, as well as visible radiation (light).
- According to the Stefan-Boltzmann law, emissivity is the quantitative comparison between the thermal radiation of a surface and that of an ideal black surface at a given temperature.
- Between 0 and 1 is the ratio's range.
<h3>What is energy radiation?</h3>
- The emissivity of a substance is a measurement of how well it reflects heat radiation from its surface.
- Two elements that affect power dissipation in the form of radiation are the material's surface emissivity and the temperature difference between the chip surface and the surrounding air.

The purpose of system is to make system more reliable and efficient for desired work completion
Explanation:
In most of the times, the system analysts operate in a dynamic environment where change is the necessary process . A business application, a business firm or a computer system may be the required environment. In order To rebuild a system, the key elements must be considered which we need to examine are as follows:
1. Outputs and inputs.
2. Security and Control.
3. processor
4. Environment.
5. Feedback.
6. Boundaries and interface.
