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.

Explanation:
(a) Find the magnitude of the angular acceleration of the wheel.
- angular acceleration = angular speed /time
- angular acceleration = 12.9/2.98 = 4.329rad/s²
(b) Find the angle in radians through which it rotates in this time interval.
- angular speed = 2x3.14xf
- 12.9rad = 2 x3.14
- rad = 6.28/12.9
- rad = 0.487
Now we convert rad to angle
- 1 rad = 57.296°
- 0.487 = unknown angle
- unknown angle =57.296 x 0.487 = 27.9°
The angle in radians = 27.9°
Answer:
1)true
2)false
3)true
4)true
5)false,cz amatter is made of atoms while light is an electromagnetic radiation.
