Answer:In non-uniform circular motion, an object's motion is along a circle, but the object's speed is not constant. In particular, the following will be true. The object's velocity vector is always tangent to the circle. The speed and angular speed of the object are not constant
Explanation:In non-uniform circular motion an object is moving in a circular path with a ... Since the speed is changing, there is tangential acceleration in ... Here is an example with an object traveling in a straight path
The balanced force is required to be acting on the window washer to keep it in the same position.
<h3>What is Force?</h3>
The external effort causing the change in the state of motion of any object is known as force.
Forces are generally of two types namely balanced force and unbalanced force.
When an object is applied with more than one force, such that net force on the object is zero and due to this the state of motion of object remains unaffected, then such type of force is called balanced force.
Similarly, the forces on the object having some net magnitude and causing some motion to the object are known as unbalanced forces.
So as per the given problem, for keeping the window washer in the same position, it is required to apply with a balanced force.
Thus, we can conclude that balanced force is required to be acting on the window washer to keep it in the same position.

Answer: His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.
Explanation:
Answer:
Downward
Explanation:
When the upper leg exerts a force on the lower leg and the combined center of gravity of both the legs lies at the center of the lower leg then the line of action of this force will be acting downwards.
- Like for any body which is placed on the other body is under the influence of gravity then the it will exert a force equal to its weight on the lower body in downward direction. Line of action of this force will be through the center of gravity of the upper body and the canter of gravity of both the bodies as a system will be the average their individual centers of the gravity.
