Answer:

blue star is hotter than red

Explanation:

The colour of a star depends on its temperature.

Lesser the temperature means lesser be the energetic. less energy means longer wavelength. Between blue and red, red colour has longer wavelength. So, the red colored star is colder than blue coloured star.

Blue coloured star is hotter than red coloured star.

<h3 /><h3>What are the qualities of stainless steel?</h3>

Stainless steel is an excellent heat conductor because it quickly warms the substance or allows heat to travel through it. Stainless steel is also corrosion-resistant.

Foam, glass, and plastic, on the other hand, are all poor heat and electrical conductors. As a result, they do not allow heat to travel through.

As a result, we may deduce that, among the available possibilities, the stainless steel container was most likely the hottest.

Hence Option Z is correct. The stainless steel container was likely the hottest.

Answer:

In the Equator:

As far as the temperature is concerned equator is more or less the same throughout the year, however, there are some fluctuations also, I will set this device in March and September because, in this month, the Sun is exactly over the equator and I would be able to get the more results in this month.

In Antarctic:

As far as the climatic conditions of Antarctic are concerned, it is all the same while it fluctuates in December because the Sun is very much close to Antarctic that's why I will choose this month.

What is velocity and speed​
NeTakaya

Answer:

velocity : velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

speed :  Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. ... An object with no movement at all has a zero speed.
