Because in reality there are frictional forces acting on the ball, against the direction of its motion. In fact, because of the friction between the ball and the surface, the ball loses little by little its energy, so its velocity decreases and eventually it stops. 
In an ideal world with no friction, there would be no forces acting on the ball, so its energy must be conserved and this means that the ball would continue its motion forever.

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

The weight of an astronaut on the moon is the same as on Earth.<br> True<br> False
Vaselesa [24]

Answer:

False

Explanation:

This is due to the gravitational pull, since the moon does not have the same force or gravity like Earth, your weight would change.

Drag and drop the correct answer to complete the sentence.
Afina-wow [57]

Answer: 10kg

Explanation:

force applied by Ahmad = 100 N

box's acceleration = 10 m/s

mass of the box = ?

Recall that Force is the product of mass of an object by the acceleration by which it moves.

i.e Force = mass x acceleration

100N = mass x 10m/s

Mass = 100N / 10m/s

Mass = 10kg

Thus, the mass of the box is​ 10kg
