Answer:
![\lambda=4.81\times 10^{-8}\ m](https://tex.z-dn.net/?f=%5Clambda%3D4.81%5Ctimes%2010%5E%7B-8%7D%5C%20m)
Explanation:
We have,
The surface temperature of the star is 60,000 K
It is required to find the wavelength of a star that radiated greatest amount of energy. Wein's displacement law gives the relation between wavelength and temperature such that :
![\lambda T=2.89\times 10^{-3}](https://tex.z-dn.net/?f=%5Clambda%20T%3D2.89%5Ctimes%2010%5E%7B-3%7D)
Here,
= wavelength
![\lambda=\dfrac{2.89\times 10^{-3}}{60000}\\\\\lambda=4.81\times 10^{-8}\ m](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7B2.89%5Ctimes%2010%5E%7B-3%7D%7D%7B60000%7D%5C%5C%5C%5C%5Clambda%3D4.81%5Ctimes%2010%5E%7B-8%7D%5C%20m)
So, the wavelength of the star is
.
After a thorough research, there exists the same question that has choices and the link of the graph (http://i37.servimg.com/u/f37/16/73/53/52/graph410.png)
<span>Choices:
A. 160 meters
B. 80 meters
C. 40 meters
D. 20 meters
E. 0 meters
</span>
The correct answer is letter E. 0 meters.
It is as a result of gravity. (D)
This is as stated by Newton's law of universal gravitation. That two objects in the universe attract one another with a force that is proportional to the product of their masses and inversely proportional to the square of the distance apart.
The constant of proportionality is the Universal Gravitational Constant.
G = 6.673 × 10⁻¹¹ Nm²kg⁻²
The amount of energy required to raise the temperature of one gram of water by one celsius degree is called a calorie.
<h3>How can you define calorie?</h3>
In physics, we can define it as a unit of measurement that defines the amount of energy to raise the temperature of 1 gram of water by 1°C. Each material has its unique calorie, however by definition we use water as it is the lowest of all the elements.
Normally, calorimetry is directly linked with the thermal capacity that an element has to contain heat.
