Answer:
a) ![F_{net}=0](https://tex.z-dn.net/?f=F_%7Bnet%7D%3D0)
b) ![T=0](https://tex.z-dn.net/?f=T%3D0)
Explanation:
From the question we are told that:
Dimensions:
![L*B=22.0*35.0cm](https://tex.z-dn.net/?f=L%2AB%3D22.0%2A35.0cm)
Current ![I=1.40A](https://tex.z-dn.net/?f=I%3D1.40A)
Magnetic field ![B=1.40](https://tex.z-dn.net/?f=B%3D1.40)
Therefore
![Area=L*B](https://tex.z-dn.net/?f=Area%3DL%2AB)
![A=22.0*35.0cm](https://tex.z-dn.net/?f=A%3D22.0%2A35.0cm)
![A=770cm=>770*0^{-4}](https://tex.z-dn.net/?f=A%3D770cm%3D%3E770%2A0%5E%7B-4%7D)
a)
Generally Force on Looping gives
![F_1-F_2](https://tex.z-dn.net/?f=F_1-F_2)
![F_3=F_4](https://tex.z-dn.net/?f=F_3%3DF_4)
Therefore
![F_{net}=0](https://tex.z-dn.net/?f=F_%7Bnet%7D%3D0)
b)
Generally the equation for Torque is mathematically given by
![T=i*Asin \theta](https://tex.z-dn.net/?f=T%3Di%2AAsin%20%5Ctheta)
Since A and B are on opposite direction
![\theta=180](https://tex.z-dn.net/?f=%5Ctheta%3D180)
Therefore
![T=1.40*770*10^{-4}sin 180](https://tex.z-dn.net/?f=T%3D1.40%2A770%2A10%5E%7B-4%7Dsin%20180)
![T=0](https://tex.z-dn.net/?f=T%3D0)
Answer:
This would have an negative affect as the permafrost melts which is the ocean can release two types of dangerous carbon gases called methane and carbon dioxide,WHich are heat trapping greenhouses gases and would make global warming worse. But also referring to the bears this forces them into competition with other bears as the ocean melts and bears are forced to move inland which is more a restricted area for hunting grounds.
