We have given
original price =150.00
discount=10%=0.1
sales tax=6%=.06
now
discount=150*0.1=15cost of bike after discount =150-15=135
sales tax=135*.06=8.1
final price =cost of bike after discount +sales tax
<span>final price=135+8.1
</span>final price=143.1<span />
<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:
The correct option is (c) "it bounces the light towards a focal point"
Explanation:
There are two types of spherical mirrors i.e. concave and convex.
A concave mirror is a type of spherical mirror that is curved inwards. For this type of mirror the rays of light are bounced back and converge to the focal point of the mirror.
So, the correct option is (c).
Answer:
Explanation:
You are not raising the temperature of the block of ice. You are making it turn phase.
H = m * hf
That's the mass of the block and the latent heat of fusion.
D.
