Answer:
Option (c)
Explanation:
The rate of change of linear momentum is called force.
As the linear motion terms are analogous to the terms in rotational motion.
So, the rate of change of angular momentum is called torque.
Answer:
B
Explanation:
did this yesterday with my friend
Hi there!
Recall the equation for angular momentum:
L = Angular momentum (kgm²/s)
I = Moment of Inertia (kgm²)
ω = angular velocity (rad/s)
We know that the Moment of Inertia of a solid cylinder is equivalent to:
M = mass (kg)
R = radius (m)
Plug in the givens to solve for the moment of inertia. Remember to divide the diameter by 2 for the radius, and to convert to meters.
We can rearrange the equation of angular momentum to solve for mass.
The option that best explains the forces acting on the objects is that option b. Objects W and Y have balanced forces, and objects X and Z have unbalanced forces.
<h3>How do you know if forces are balanced or unbalanced?</h3>
When the motion of an object is said to be altered, the forces are known to be in a sate that is seen as unbalanced.
Note that Balanced forces are said to be one that are equal in size and also opposite in direction.
Hence, if forces are balanced, there is no alteration in motion and it is seen in cases if a person is pushed or pulled on an object that is seen from opposite directions but also has the same force.
Therefore, The option that best talks about the forces acting on the objects is that option b. Objects W and Y have balanced forces, and objects X and Z have unbalanced forces as it does better justice to it.
