Answer:
90-100meters
Explanation:
The overall length limitation of a UTP cable is 90-100meters. Once this limitation is reached, a repeater is employed to transfer data.
Answer: Heat energy is transferred from warmer objects to cooler objects.

Answer:
![I=2.6363\ kg.m^2](https://tex.z-dn.net/?f=I%3D2.6363%5C%20kg.m%5E2)
Explanation:
Given:
dimension of uniform plate, ![(0.673\times 0.535)\ m^2](https://tex.z-dn.net/?f=%280.673%5Ctimes%200.535%29%5C%20m%5E2)
mass of plate, ![m=10.7\ kg](https://tex.z-dn.net/?f=m%3D10.7%5C%20kg)
Now we find the moment of inertia about the center of mass of the rectangular plate is given as:
![I_{cm}=\frac{1}{12} \times m(L^2+B^2)](https://tex.z-dn.net/?f=I_%7Bcm%7D%3D%5Cfrac%7B1%7D%7B12%7D%20%5Ctimes%20m%28L%5E2%2BB%5E2%29)
where:
length of the plate
breadth of the plate
![I_{cm}=\frac{1}{12} \times 10.7\times(0.673^2+0.535^2)](https://tex.z-dn.net/?f=I_%7Bcm%7D%3D%5Cfrac%7B1%7D%7B12%7D%20%5Ctimes%2010.7%5Ctimes%280.673%5E2%2B0.535%5E2%29)
![I_{cm}=0.6591\ kg.m^2](https://tex.z-dn.net/?f=I_%7Bcm%7D%3D0.6591%5C%20kg.m%5E2)
We know that the center of mass of the rectangular plane is at its geometric center which is parallel to the desired axis XX' .
Now we find the distance between the center of mass and the corner:
![s=\frac{\sqrt{ (0.673^2+0.535^2)}}{2}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B%5Csqrt%7B%20%280.673%5E2%2B0.535%5E2%29%7D%7D%7B2%7D)
![s=0.4299\ m](https://tex.z-dn.net/?f=s%3D0.4299%5C%20m)
Now using parallel axis theorem:
![I=I_{cm}+m.s^2](https://tex.z-dn.net/?f=I%3DI_%7Bcm%7D%2Bm.s%5E2)
![I=0.6591+10.7\times 0.4299^2](https://tex.z-dn.net/?f=I%3D0.6591%2B10.7%5Ctimes%200.4299%5E2)
![I=2.6363\ kg.m^2](https://tex.z-dn.net/?f=I%3D2.6363%5C%20kg.m%5E2)
Answer:
less than stating velocity due to friction and air resistance.
Explanation:
The gravitational energy is going up subtracting the energy that was on the ground
