<span>Torque = I * α
I = ½ * m * r^2 = ½ * 0.2 * 0.125^2 = 0.0015625
As the disk rotates one time, it rotates an angle of 2 π radians.
Total angle = 1600 * 2 π = 3200 * π
One minute is 60 seconds. To determine its initial angular velocity, divide this angle by 60.
ω = 53⅓ * π
This is approximately 167.55 rad/s. To determine the angular acceleration, divide by 4.1 seconds.
α = 53⅓ * π ÷ 4.1
This is approximately 4.09 rad/s^2
Torque = 0.0015625 * (53⅓ * π ÷ 4.1)
This is approximately 0.0639 N * m.

Answer:
a= 2.667 m/s²
Explanation:
Given that
Initial velocity ,u= 2 m/s
Final velocity ,v= 10 m/s
Time taken ,t= 3 s
As we know that
v = u + at
a=Acceleration ,u=Initial velocity ,v= Final velocity ,t=time
Now by putting the values in the above equation
v = u + at
10 = 2 + a x 3
8 = 3 a
a= 2.667 m/s²
Therefore the acceleration of the biker will be 2.667 m/s²
I believe its A

By inductive and deductive reseachhhhh
For number one she is going to observe the contraction of the ballon
For number two she is going to observe the expansion of the ballon
Opposite charges attract; like charges repel :)
