Answer:
The torque on the loop is Nm
Explanation:
Given:
Current A
Magnetic field T
Area of loop
Angle between magnetic field and area vector 21°
Form the formula of torque in case of magnetic field,
г
Where magnetic moment
г
г
г Nm
Therefore, the torque on the loop is Nm
Answer:
The answer is a wedge.
Explanation:
The wedge is a combination of two inclined planes. It is used to separate bodies which are held together by large forces, e.g, splitting timber
M.A.= slant height of wedge/thickness of wedge.
Hence a long thin wedge has a higher mechanical advantage than a short thick one; or the smaller the angle theta between the slant heights, the greater the mechanical advantage.
