Answer:
The linear velocity is 
Explanation:
According to the law of conservation of energy
The potential energy possessed by the hoop at the top of the inclined plane is converted to the kinetic energy at the foot of the inclined plane
The kinetic energy can be mathematically represented as

Where
is the moment of inertia possessed by the hoop which is mathematically represented as
Here R is the radius of the hoop
is the angular velocity which the hoop has at the bottom of the lower part of the inclined plane which is mathematically represented as

Where v linear speed of the hoop's center of mass just as the hoop leaves the incline and rolls onto a horizontal surface
Now expressing the above statement mathematically


=>
=> 
=> 
=> 
Substituting values


Answer:
Explanation:
When the two or more forces acting on a body such tat the net force on the body or the acceleration of the body is zero, then such forces are balanced forces.
For example, in the game of tug of war, both the teams pulls the rope with same force but in opposite directions so that the net acceleration is zero it means a balanced force is acting on the rope.
When tow or more forces acting on a body and there is some net force or acceleration of the body, then the forces are said to be unbalanced.
For example, if we push a box along the plane, the net force is non zero and the forces are unbalanced.
Answer:
99 V
Explanation:
The effective voltage of an AC current (also called rms voltage) is given by

where
Vrms is the rms voltage
V0 is the peak voltage
In this problem, we know the effective voltage:

Therefore, we can re-arrange the equation to find the peak voltage:
