<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.

Answer:
Area is a scalar quantity because there is no need of direction to define and also follow the algebraic summation. When we talk about vector there exists a frame of reference with a certain origin. It actually depends on the fact of the physical area, but if that factor changes to a non-directional object such as a rug spread on the floor, you can consider the area or a region as a scalar. (*Scalars are quantities that are fully described by a magnitude (or numerical value) alone.)

After fertilization in the fallopian tube, It will take 6-12 days for the zygote to travel before arriving at the uterus.
<h3>What is a zygote?</h3>
A zygote is, generally speaking, a cell created by the fusion of two gametes; the growing person is created from such a cell.
It takes the zygote around 6–12 days following fertilization in the fallopian tube for the fertilized egg to travel to the uterus and attach to the uterus, a process known as implantation.
Hence It will take 6-12 days for the zygote to travel before arriving at the uterus.

2.04 meters distance is traveled by the sled before stopping.
Mass of the sled = m
The initial speed of the sled = 2 m/s
Coefficient of kinetic friction between sled and ice = 0.100
Let the distance the sled moves before it stops be d.
Gravity = 9.8 m/ s²
Let the initial kinetic energy sled be
The work done by the frictional force is,
Work done by frictional force= Initial kinetic energy of the sled
So, the distance traveled by the sled before stopping is
Therefore, the distance traveled by the sled before stopping is 2.04 meters.

Answer:
The pattern would spread out.
Explanation:
The fringe width is given by the relation
fringe width = λ L / D where λ is wavelength of light used, L is distance of wall from the source of light and D is slit separation.
If we increase λ , fringe width will increase and therefore pattern will spread out .
