The Kinetic energy would be 1/2IL².

<h3>What is Rotational Kinetic energy ?</h3>

  • Rotational energy also known as angular kinetic energy is defined as: The kinetic energy due to the rotation of an object and is part of its total kinetic energy. Rotational kinetic energy is directly proportional to the rotational inertia and the square of the magnitude of the angular velocity.

As we know linear Kinetic energy = 1/2mv²

 where m= mass and v= velocity.

Similarly rotational kinetic energy is given by = 1/2IL²

 where I- moment of inertia and L=angular momentum.

Answer:

Resultant = 3.05N

Explanation:

r =  \sqrt{{5}^{2} + 5^{2} - 2(5)(5) \cos(120) }

r =  \sqrt{25 + 25 - 50(0.8142)}

r =  \sqrt{50 - 40.71}  =  \sqrt{9.29}

r = 3.05

During the operation of fan we know that it is working on the electricity

So here when we connect the fan with electricity it uses the electrical energy and convert that energy into mechanical energy of fan

Fan uses this electrical energy to rotate the blades of fan and then it gives the high speed air to us

So here correct answer must be

B.

Which best describes the weak nuclear force? It is weaker than the gravitational force, with a greater range than the weak nucle
labwork [276]

Weak nuclear force is weaker than the strong nuclear force with a smaller range than the electromagnetic force.

It acts between fermions with spin 1/2 basically quarks and leptons. It has a range of 10⁻¹⁸ meters.

Option 1 is incorrect. It is stronger than the gravitational force.

Option 2 is incorrect. It is weaker than the electromagnetic force.

Option 3 is incorrect. It has a smaller range than the strong nuclear force.
