The direction of torque τ this method is mathematically given as
D=X
Option A is correct.
<h3>What is the
direction of
torque?</h3>
Generally, the equation for torque is mathematically given as
τ = r X F
Hence to decipher the torque direction with respect to the center of mass of the body due to force F acting on the body at a location indicated by the vector r
- We utilize our right hand.
- Place our right-hand fingers along the path of r
- Place our right-hand palm on F
- Then slowly we sweep r into F.
- The path or direction of the thumb will provide the direction of the torque.
In conclusion, the direction of this method is
D=X Option A.

Answer:
<h2>
16,931 turns</h2>
Explanation:
The magnetic field produced is expressed using the formula
B is the magnetic field = 0.30T
I is the current produced in the coil = 4.5A
is the magnetic permittivity in vacuum = 1.26*10^-6Tm/A
L is the length of the solenoid = 32 cm = 0.32 m
N is the number of turns in the solenoid.
Making N the subject of the formula from the equation above;
Substituting the give values to get N;
The number of turns the solenoid must have is approximately 16,931 turns
I think it is equal for your question
Work is force multiplied by the distance the force moves the object
