Answer:
It is located at a distance of 5.94 light years from Earth.
Explanation:
Since light transmitted from the star takes approximately 5.94 years to reach the earth, it means the star is located at a distance of 5.94 light years from Earth.
Answer:
1.99 parsecs.
Explanation:
We have been given that the most recently discovered system close to Earth is a pair of brown dwarfs known as Luhman 16. It has a distance of 6.5 light-years.
We know that one light year equals to 0.306601 parsecs. To convert 6.5 light-years to parsecs, we will multiply 0.306601 by 6.5.
Therefore, Luhman 16 is approximately 1.99 parsecs away from the Earth.
Answer:
Calorimetry
Explanation:
In the calorimetry experiments, mix a known amount of a high temperature material, about 100 ° C, with an equivalent amount of water at room temperature. In a device thermally isolated from the environment, and the initial and final temperatures of liquid and solid are analyzed and energy conservation relationships, the specific heat of the unknown material can be found.
When you lay down your weight is distributed over a much larger surface area than while standing. You are putting a much greater force on a much smaller area standing.
