Answer:
Magnitude of the resultant force will be 20N in the direction of
.
Explanation:
It's given in the question that two forces have been applied on the object given.
Since force is a vector quantity, therefore, it has magnitude and direction both.


Both the forces are in the opposite directions.
Therefore, magnitude of the resultant force of these forces will be,

= 20 N
And the direction of the resultant force will be towards
.
Therefore, magnitude of the resultant force will be 20N in the direction of
.
Velocity differs from speed in that velocity indicates a particle's <span>direction of motion.
Therefore, your correct answer is: D</span><span>irection
Good luck with your studies, I hope this helps~!</span>
Answer:
linear acceleration

angular acceleration

Explanation:
As we know that the force due to tension force is upwards while weight of the disc is downwards
so we will have

also we have

now we have


now we have


so we have
linear acceleration

angular acceleration

<span>120 revolutions per min is (20RPM)
120revolutions is 240 Pi radians (because 1 revolution is 2Pi rad)
angular velocity
w= 240Pixf, f is the frequency and f= 1/T, T =1mn=60s=period, so f=1/60=0.01Hz
so w = 240*Pi*0.01=12.56 rad /s
linear velocity can be found with
V =Rx w,
V=12.56 R the value depends on what value is the radius of both wheels
