Answer:
It decreases.
Explanation:
between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases
The most important mineral resources of Virginia are coal, crushed stone, sand and gravel, lime (from limestone and dolostone) and natural gas.
Answer:
So magnetic field will be equal to 0.1144 T
Explanation:
We have given frequency f = 60 Hz
Maximum emf e = 5500 volt
Number of turns N = 150
Area ![A=0.85m^2](https://tex.z-dn.net/?f=A%3D0.85m%5E2)
Emf generated in ac generator is given ![e=NBA\omega sin(\omega t)](https://tex.z-dn.net/?f=e%3DNBA%5Comega%20sin%28%5Comega%20t%29)
For maximum emf ![sin(\omega t)=1](https://tex.z-dn.net/?f=sin%28%5Comega%20t%29%3D1)
So maximum emf will be equal to ![e=NBA\omega](https://tex.z-dn.net/?f=e%3DNBA%5Comega)
![B=\frac{e}{NA\omega }=\frac{5500}{150\times 2\times 3.14\times 60\times 0.85}=0.1144T](https://tex.z-dn.net/?f=B%3D%5Cfrac%7Be%7D%7BNA%5Comega%20%7D%3D%5Cfrac%7B5500%7D%7B150%5Ctimes%202%5Ctimes%203.14%5Ctimes%2060%5Ctimes%200.85%7D%3D0.1144T)
So magnetic field will be equal to 0.1144 T
