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.
motion energy
Answer:
K_{total} = 19.4 J
Explanation:
The total kinetic energy that is formed by the linear part and the rotational part is requested
let's look for each energy
linear
= ½ m v²
rotation
= ½ I w²
the moment of inertia of a solid sphere is
I = 2/5 m r²
we substitute
= ½ mv² + ½ I w²
angular and linear velocity are related
v = w r
we substitute
K_{total} = ½ m w² r² + ½ (2/5 m r²) w²
K_{total} = m w² r² (½ + 1/5)
K_{total} = 
m w² r²
let's calculate
K_{total} = 6.40 16.0² 0.130²
K_{total} = 19.4 J

Answer:
100 percent
Explanation:
Relative humidity is the water-vapour content of the air relative to its content at saturation. Saturated air, for example, has a relative humidity of 100 percent, and near the Earth the relative humidity very rarely falls below 30 percent.
I think it is that protons are stuck with the neutrons in a strong force that is in the nucleus
