Answer:
In other words, Tension (Ft) = Force of gravity (Fg) = m × g. Assuming a 10 kg weight, then, the tension force is 10 kg × 9.8 m/s2 = 98 Newtons.

Answer:
0.011 N-m
Explanation:
Given that
The mass of a solid cylinder, m = 30 kg
The radius of the cylinder, r = 0.18 m
The acceleration of the cylinder,
It rotates about an axis through its center. We need to find the torque acting on the cylinder. The formula for the torque is given by :
Where
I is the moment of inertia of the cylinder,
For cylinder,
So,
So, the required torque on the cylinder is 0.011 N-m.
The answer is D
The reason being because the singular replacement has the first letter of each side swap
For Example: A+BC —> B+AC
Answer: The speed is not constant and the object is performing a non uniform circular motion
Explanation:
Let's begin by explaining that the centripetal force is proportional to the centripetal acceleration of an object moving in circular motion is given by the following equation:
Where:
is the velocity
is the radius of the circle
In uniform circular motion, <u>the centripetal acceleration vector is always perpendicular to the velocity vector</u>, hence, the speed (the magnitude of velocity vector) is constant.
However, if a component of the centripetal acceleration vector is not perpendicular (is parallel to the velocity vector): the speed is not constant, the net force acting on the object will not be perpendicular to its motion and we will be dealing with <u>non uniform circular motion.</u>
It is important to note that in this situation the motion needs a tangential force, as well. Being the tangential acceleration proportional to and the angular acceleration :
