τismaxiμmwhensinθ=90∘τismaxiμmwhensinθ=90∘
τmax=niabsin90∘=mbτmax=niabsin90∘=mb
=50×5×3.14×4×10−4×2×10−1=50×5×3.14×4×10-4×2×10-1
=6.28×10−2Nm=6.28×10-2Nm
Given τ=12×τmaxτ=12×τmax
⇒sinsinθ=12⇒sinsinθ=12 or sinθ=30∘sinθ=30∘
=∠betweenareavar→randmag≠ticfield=∠betweenareavar→randmag≠ticfield.
So angle between magnetic field and the plane of the coil
=90∘−30∘=60∘=90∘-30∘=60∘.

The air that was inside the balloon will expand to fill the room
Explanation:
Matter exists in three states:
- Solid: in a solid, the molecules are bound to each other by strong intermolecular bonds, so they are not able to move freely, but only to vibrate around their fixed position. As a result, solids have a definite shape and a definite volume.
- Liquid: in a liquid, the molecules are free to slide past each other, however there are still intermolecular forces acting between them that prevent them to move too far apart from each other. As a result, liquids have a definite volume, but not a definite shape.
- Gas: in a gas, intermolecular forces between molecules are negligible, and molecules can move freely. As a result, gases have no definite volume and no definite shape.
According to the definition of gas, this means that in this problem, when the air is released from the balloon, the molecules of air will move out of it and will try to fill the whole space available, which is the room.

At the subduction zone a very deep trench is formed in the ocean floor. Oceanic and oceanic plate convergence result in the formation of volcano chains. The crust that is pulled under or subducted melts to form magma. This magma rises to the top of the overriding oceanic plates and erupts on the ocean floor.
So the answer would be Volcano
