The question is incomplete, the complete question is;
Each sentence describes potential and kinetic energy at various locations on a slide. Complete each statement by selecting the position of the object on the slide.
An object at position has all kinetic energy. A B or C
An object at position has all potential energy. A B or C
An object at position has about half potential energy and half kinetic energy. A B or C
Answer:
An object at position C has all kinetic energy.
An object at position A has all potential energy.
An object at position B has about half potential energy and half kinetic energy.
Explanation:
Lets take a good look at the image.
At position A, the object is stationary and we know that the energy possessed by an an object by virtue of its position is known as potential energy. Hence at A, the energy possessed by the body is all potential.
At position B, the total mechanical energy of the object becomes potential energy + kinetic energy as the object is now in motion.
At position C, the object is still in motion and the energy is all kinetic.
Answer:
<h2>Volume = 6 cm³</h2>Explanation:
Density of a substance is given by
From the question
Density = 4.0 g/cm³
mass = 24g
Substitute the values into the above formula and solve for the volume
That's
Divide both sides by 4
v = 6
We have the final answer as
<h3>Volume = 6 cm³</h3>Hope this helps you
