How much work is done on an object if 10 newtons of force are applied to the object and it moves 2 meters? a. 0.2 j b. 5 j c. 8 j d. 20 j

Answer is D..by applying formula W=Fs ..10×2 = 20

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.

A. they hold atoms  together with a molecule.its a force that exist between molecules. hope this .
