Answer:
the two objects are in thermal equilibrium
Explanation:
thermal equilibrium us the state where two bodies or objects have the same amount of temperature thus no heat conduction
Answer:
It was created during the French Revolution in 1799 and has enabled for the international exchange of scientific and technical information. Calculating with SI units is also a lot easier than using the English system.
D) because they only reflect light
The gravitational force on two objects can be determined by the following equation:
![F=G\frac{m_{1}m_{2}}{r^2}](https://tex.z-dn.net/?f=F%3DG%5Cfrac%7Bm_%7B1%7Dm_%7B2%7D%7D%7Br%5E2%7D)
Where G is the gravitational constant m1 is mass 1, m2 is the second mass nad r^2 is distance between these objects. Therefore, let m1 = mass of Sun 1.99x10^30 kg, m2= mass of Jupiter 1.90x10^27 kg, r is the average distance between the Sun and Jupiter 7.78x10^11 m. By plugging these values in we have:
![F=6.67x10^{-11}\frac{(1.99x10^{30})(1.90x10^{27})}{(7.78x10^{11})^2}](https://tex.z-dn.net/?f=F%3D6.67x10%5E%7B-11%7D%5Cfrac%7B%281.99x10%5E%7B30%7D%29%281.90x10%5E%7B27%7D%29%7D%7B%287.78x10%5E%7B11%7D%29%5E2%7D)
![F=4.1665x10^{23}](https://tex.z-dn.net/?f=F%3D4.1665x10%5E%7B23%7D)
F=4.17x10^23 N
Answer:
![1.3922\times 10^{-8}\ s](https://tex.z-dn.net/?f=1.3922%5Ctimes%2010%5E%7B-8%7D%5C%20s)
Explanation:
= Distance covered = 1 m
= Time taken = 3.44 ns
c = Speed of light = ![3\times 10^8\ m/s](https://tex.z-dn.net/?f=3%5Ctimes%2010%5E8%5C%20m%2Fs)
Velocity would be
![v=\frac{\Delta x}{\Delta t_l}\\\Rightarrow v=\frac{1}{3.44\times 10^{-9}}\\\Rightarrow v=290697674.4186\ m/s](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B%5CDelta%20x%7D%7B%5CDelta%20t_l%7D%5C%5C%5CRightarrow%20v%3D%5Cfrac%7B1%7D%7B3.44%5Ctimes%2010%5E%7B-9%7D%7D%5C%5C%5CRightarrow%20v%3D290697674.4186%5C%20m%2Fs)
Time in rest frame is given by
![\Delta t'=\frac{\Delta t_l}{\sqrt{1-\frac{v^2}{c^2}}}\\\Rightarrow \Delta t'=\frac{3.44\times 10^{-9}}{\sqrt{1-\frac{290697674.4186^2}{(3\times 10^8)^2}}}\\\Rightarrow \Delta t'=1.3922\times 10^{-8}\ s](https://tex.z-dn.net/?f=%5CDelta%20t%27%3D%5Cfrac%7B%5CDelta%20t_l%7D%7B%5Csqrt%7B1-%5Cfrac%7Bv%5E2%7D%7Bc%5E2%7D%7D%7D%5C%5C%5CRightarrow%20%5CDelta%20t%27%3D%5Cfrac%7B3.44%5Ctimes%2010%5E%7B-9%7D%7D%7B%5Csqrt%7B1-%5Cfrac%7B290697674.4186%5E2%7D%7B%283%5Ctimes%2010%5E8%29%5E2%7D%7D%7D%5C%5C%5CRightarrow%20%5CDelta%20t%27%3D1.3922%5Ctimes%2010%5E%7B-8%7D%5C%20s)
