Answer:
I can't understand the language....
Answer:
b) false
Explanation:
Since in the given situation it is mentioned that the mass conversation would be simple and same applied to the fluids with care also the conservation of momentum would be applied to any type of closed system like collisions
But as we know that
In the inelastic collisions, the total kinetic energy would not be remain conserved
So the given statement is false
Answer:
Explanation:
From the question we are told that:
Radius 
Current 
Normal vector 
Magnetic field 
Generally the equation for Area is mathematically given by
Generally the equation for Torque is mathematically given by
Where
![X\ component\ of\ i'*B= [(-1 * 0)-(2*-6)]](https://tex.z-dn.net/?f=X%5C%20component%5C%20of%5C%20i%27%2AB%3D%20%5B%28-1%20%2A%200%29-%282%2A-6%29%5D)
Therefore
