<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 universal force that is the weakest is gravitational. The correct answer is B.
Answer:
The rate of doing work is called power.
Lodestone is a naturally magnetized piece of the mineral magnetite
The amount of current is the same through any component in a series circuit. Resistance: The total resistance of any series circuit is equal to the sum of the individual resistances. Voltage: The supply voltage in a series circuit is equal to the sum of the individual voltage drops.
